Review: Convert CM to Inches
Before we learn how to convert cm to inches, let’s review some key vocabulary related to this topic.
What are centimeters (cm) and inches (in.)?
A centimeter is a metric unit of length that is equivalent to one hundredth of a meter. The abbreviation for centimeters is cm.
An inch is an imperial unit of length that is equivalent to one twelfth of a foot. The abbreviation for inches is in.
Note that most of the world uses the metric system of measurement, while the imperial system in most commonly used in the United States.
When we compare the metric system and the imperial system in terms of inches and centimeters, the cm to inches unit conversion is as follows:
1 inch equals 2.54 centimeters.
This relationship between inches and centimeters is shown in Figure 01 above.
CM to Inches Formula
Now that we understand the relationship between centimeters and inches, we are ready to learn the formula for how to convert cm to inches.
CM to Inches Conversion Formula:
Inches = Centimeters ÷ 2.54
So, whenever to have a length expressed in cm that you want to convert to inches, simple divide that length, in cm, by 2.54 (since one inch equals 2.54 centimeters), and then express your result in terms of inches.
Figure 02: How to convert cm to inches in 3 easy steps.
How to Convert CM to Inches in 3 Steps
You can use the conversion formula to solve any problem where you have to convert centimeters to inches by following these three easy steps:
Step 1: Identify the given length (in cm).
Step 2: Input that length into the conversion formula (inches = cm ÷ 2.54)
Step 3: Round your answer (if necessary) and express it in terms of inches.
For example, let’s convert 10 centimeter to inches using these three steps:
Step 1: Identify the given length (in cm).
The given length is 10 cm.
Step 2: Using the formula:
inches = cm ÷ 2.54
inches = 10 ÷ 2.54
inches = 3.937007874…
Step 3: Round your answer.
In most cases, you can make an accurate and correct conversion by rounding your answer to the nearest tenths decimal place.
Final Answer: 10 cm equals 3.94 inches.
Figure 02 above illustrates how we used the conversion formula to determine that 10 centimeters equals approximately 3.94 inches.
Now, let’s gain some more experience with converting cm to inches by working through some more practice problems.
CM to Inches Conversion Formula: inches = cm ÷ 2.54
CM to Inches: Example #1
Example #1: Convert 15 cm to inches
We can use our 3-step method to solve this problem as follows:
Step 1: Identify the given length (in cm).
For this example, the given length is 15 cm.
Step 2: Using the cm to inches conversion formula:
inches = cm ÷ 2.54
inches = 15 ÷ 2.54
inches = 5.9055118…
Step 3: Round your answer.
Finally, we can round our answer to the nearest tenths decimal place and conclude that:
Final Answer: 15 cm equals 5.90 inches.
Example #1 Solved: 15 cm equals 5.90 inches.
CM to Inches: Example #2
Example #2": Convert 19.5 cm to inches
We can solve this next example exactly the same way that we did Example #1
Step 1: For Example #2, the given length is 19.5 cm.
Step 2: Next, input 19.5 cm into the conversion formula as follows:
inches = cm ÷ 2.54
inches = 19.5 ÷ 2.54
inches = 7.677165…
Step 3: After rounding our result to 7.68, we can say that…
Final Answer: 19.5 cm equals 7.68 inches.
Example #2 Solved: 19.5 cm equals 7.68 inches
CM to Inches: Example #3
Example #3: A picture frame is 41 cm wide and 51 cm tall. What are the dimensions of the picture frame in inches? Round your answer to the nearest inch.
For our final example, we have to make to cm to inches conversions:
Convert 41 cm to inches; and
Convert 51 cm to inches
We can make the first conversion by using the cm to inches conversion formula as follows:
41 cm to inches
inches = cm ÷ 2.54
inches = 41 ÷ 2.54
inches = 16.1417…
41 cm equals approximately 16 inches
And, we can use the same approach to make the second conversion:
51 cm to inches
inches = cm ÷ 2.54
inches = 51 ÷ 2.54
inches = 20.07874
51 cm equals approximately 20 inches
Now that we have made both conversions, we can conclude that:
Final Answer: The approximate dimensions of the frame are 16 inches by 20 inches.
Example #3 Solved: The dimensions of the frame are 16 inches by 20 inches.

Reflection Over X Axis and Y Axis: Student GuideMath Skills: Perform a reflection over x axis, Perform a reflection over y axis, Reflections on the coordinate planeUnderstanding how to perform a reflection over x axis or a reflection over y axis is an important algebra skill that students can easily master with some study and practice. In real life, a reflection is a concept that everyone is familiar with, as many of us look a mirror at least once every day. Similarly, in math, a reflection is a type of transformation where the mirror image of a point, line, or figure is displayed on the coordinate plane. This free student guide on How to Perform Reflection Over X Axis and How to Perform Reflection Over Y Axis will teach you how to perform reflections on the coordinate plane in a simple step-by-step way. Table of Contents | Jump to: Reflections in Real-Life (Photo by Tim Stief via Unsplash) Reflections in Math: Reflection over the x axis example. What is a Reflection Over the X-Axis?In math, a reflection over x axis of a point, a line, or a figure involves reflecting the image over the x axis to create a mirror image. In the case of a reflection over the x axis, the horizontal line on the coordinate plane that passes through the origin (the x-axis) would be called the axis of reflection. In other words, whenever something is reflected over the x axis, it is essentially “flipped” across the axis on the coordinate plane. Rule: Whenever a point is reflected over the x-axis, the following rule applies:
For example, if we reflected the coordinate points A (2,6) and B (7, 3) over the x-axis, the new reflected points, A’ and B’, would become:
Again, notice, after a reflection over x axis, that the x-coordinates did not change, but the signs of the y-coordinates were reversed (positive values became negative) Figure 01 below shows what it would look like if we took line segment AB (with coordinates A (2,6) and B (7, 3)) and reflected it over the x-axis to create the image of line segment A’B’. Figure 01: The reflection over x axis rule states that (x,y) → (x,-y). What is a Reflection Over the Y-Axis?Similarly, a reflection over y axis of a point also involves reflecting the image over the y axis to create a mirror image. Whenever you have to reflect a point over the y axis, you are reflecting over the vertical line on the coordinate plane that passes through the origin (i.e. the y-axis is the axis of reflection). Rule: Whenever a point is reflected over the y-axis, the following rule applies:
For example, if we took line segment AB, with coordinate points A (2,6) and B (7, 3), from the previous example and reflected over y axis, the new coordinate points, A’ and B’, would be:
In the case of reflection over y axis, notice that the signs of the x-coordinate values were reversed (positive became negative) and that the y-coordinate values were unchanged. Figure 02 below illustrates this rule and what the image of AB would look like after it was reflected over the y axis. Figure 02: The reflection over y axis rule states that (x,y) → (-x, y). The chart below displays the difference between reflecting line segment AB over the x-axis versus reflecting over the y-axis.
Now that you have a better understanding of the difference between a reflection over x axis and a reflection over y axis, you are ready to work through a few practice problems. Before moving onto the next section, make sure that you have a firm grasp of the following key points:
Figure 03: The x-axis is a horizontal line and the y-axis is a vertical line. Reflection Over X Axis and Y Axis ExamplesReflection Over X Axis Example #1Problem: Reflect the point P (5,8) over the x-axis. For our first example, we will take a given point and perform a reflection over x axis. Quick Tip: Remember that the rule for reflecting a coordinate point over the x-axis is (x,y) → (x,-y), so you only have the change the sign of the y-coordinate. Step 1: Apply the reflection over the x-axis rule:
Step 2: Plot P’ (5,-8) on the coordinate plane to complete the reflection.
Example #1: Reflection over x axis of one coordinate point. Reflection Over X Axis Example #2Problem: Reflect line segment RS, with endpoints R(-3,-4) and S(2,-5), over the x axis. For this next example of how to perform reflection over x axis, we have to reflect an entire line segment, and we can do that by applying the rule (x,y) → (x,-y) to both endpoints and then plotting those new points and constructing the line segment R’S’. Step 1: Apply the rule to each given point.
Example #2: Reflection over x axis of a line segment. Step 2: Plot the endpoints R’ and S’ and construct the reflected line segment (i.e. connect R’ and S’ with a straight line). Final Answer: The reflected line segment R’S’ has endpoints at R’ (-3, 4) and S’ (2, 5). The chart below shows how the coordinates of points R and S were transformed after a reflection over the x axis.
Reflection Over X Axis Example #3Now, let’s try a problem where we have to reflect an entire figure over the x-axis. Problem: Reflect △ABC over the x-axis if the figure has vertices at:
Step 1: Apply the rule (x,y) → (x,-y) to each point:
Example #3: Reflection over x axis of a figure. Step 2: Plot and label points A’, B’, and C’ on the coordinate plane and construct △A’B’C’ as shown in Figure 04 below. Notice how points A and B are reflected below the x-axis, while point C is reflected above the x-axis, which creates a symmetrical mirror image between △ABC and △A’B’C’. Figure 04: How to perform a reflection over the x axis of a figure (completed) Reflection Over Y Axis Example #1Problem: Reflect the point K (-8,6) over the y-axis. Let’s start off by reflecting a single coordinate point over the y axis. Quick Tip: The rule for reflecting a point over the y-axis is (x,y) → (-x,y), so you only have the change the sign of the x-coordinate. Step 1: Apply the reflection over y-axis rule:
Step 2: Plot K’ on the graph. Final Answer: After K (-8,6) is reflected over the y-axis, the coordinates of K’ are (8,6). Example #1: Reflection over y axis of a point. Reflection Over Y Axis Example #2Our next example of how to perform reflection over y axis involves a line segment. Problem: Reflect segment CD over the y-axis, where:
Step 1: Apple the rule (x,y) → (-x,y) to each point:
Step 2: Plot C’ and D’ and construct the reflected line segment C’D’. Final Answer: Line segment C’D’ has endpoints at C’ (-2,7) and D’ (-9,-5). Example #2: Reflection over y axis of a line segment. The chart below shows how the coordinates of points C and D were transformed after a reflection over the y axis.

Free Printable Division Chart for Kids Division Chart for StudentsIf your kids are learning how to divide, then a division chart is an effective and useful visual tool for helping them to learn division facts and understand patterns and relationships related to division. While using a multiplication chart to learn multiplication facts and times tables is a common practice at the elementary level, using a division chart to learn division facts is less common. However, division charts can be extremely effective when it comes to helping kids to learn how to divide and to study and remember relationships related to division. If you are looking for a printable reference that includes division facts for the numbers 1-12, our handy free division chart is an awesome tool that can help students in a variety of ways. Having a decimal chart nearby when learning how to divide numbers and how to solve elementary division problems is a great way to support students and help them to learn their division facts. Below you will find a link to download your free Fraction Chart as a printable PDF file. The entire division chart fits on one page, and it can be printed in color or in black-and-white. Division Chart (Preview) Division Chart DownloadClick Here to Download Your Free Division Chart PDF (When you click on the text link above, the PDF preview window will appear, where you will have the option download and/or print your division chart). Now that you have your Division Chart on hand, here are a few great ideas for how you can use division charts to support your students in your classroom or your kids at home. How to Use a Division Chart to Help Your StudentsWhen it comes to helping young learners with complex topics like multiplication and division, visual tools can be an incredibly effective resource for helping students to develop both procedural fluency as well as conceptual understanding. In the case of learning how to divide whole numbers, using a division chart is a great way to help students learn important division facts and how to perform basic division. Additionally, once students have become familiar with multiplication and multiplication charts, they can use a division chart to better understand the inverse relationship between multiplication and division. If you are looking for a few specific ways to use a division chart to help your students with this important math skill, here are a few ideas: Learning Important Math Facts Similar to how multiplication tables help students to understand and remember common multiplication facts, a division chart can help students to understand and remember common division facts. For example, students who memorize that 8 x 3 = 24 and also that 24 ÷ 8 = 3 are better able to make quick and accurate computations and solve problems. They are also better able to understand the relationship between multiplication and division. A division chart is a great too for supporting students during independent practice. (Image: Mashup Math G) Support Kids at Home and in the Classroom One of the best ways to use a Division Chart to help your kids at home is to print it out and have it laminated so that you can use it as a reference guide as often as you need to. When students are first learning how to divide and doing independent practice at home, having a physical division chart nearby can support students whenever they are struggling with solving a problem. This strategy also works for students in the classroom, as teachers can either post a division chart in their classroom, or give each student their own division chart to use as a reference. In either scenario, students who have a hard time with remembering division facts can use a division chart to support their learning, build confidence, and prevent them from becoming overly frustrated when they are struggling. Check Your Work As your students become more comfortable and confident in their division skills, they will not need to have a division chart as reference as often. When your students reach this level, you can have them work on work on solving division problems on their own, and then they can self-assess by checking their answers using a division chart once they have completed an assignment. This strategy helps students to identify their strengths and weaknesses, and what particular division facts they need to practice more and study further. Recognizing Patterns and Relationships Once your students are able to divide whole numbers consistently, you can start to give them assignments that mix multiplication problems and division problems together. At this level, having students look at multiplication charts and division charts side-by-side is a great way to help students to deeply understand the relationship between multiplication and division, which will help them to solve more complex and multi-step problems in the future. For example, consider having students work on these two problems one after the next:
After students solve both problems, students are better able to understand why multiplication and division are inverse operations of each other. By helping your students develop a strong foundational understanding of division, how to divide numbers, and the inverse relationship between division and multiplication, you are putting your students on a path to be successful at higher levels of math, which will benefit them in the classroom and beyond.
