Step 1: Understand the Conversion

First, it is important to understand the conversion factor between centimeters (cm) and inches (in). One inch is equal to 2.54 centimeters. This means that to convert from centimeters to inches, we need to divide the length in centimeters by 2.54.

Step 2: Write Down the Calculation

To convert from cm to in, we can use the following formula:

Length in inches = (length in centimeters) / 2.54

Step 3: Use a Calculator (Optional)

If you are more comfortable using a calculator to perform the conversion, you can simply input the number of centimeters and divide it by 2.54 to get the equivalent length in inches.

Step 4: Example Calculation

Let’s say you have a length of 50 cm that you want to convert to inches. We can use the formula from step 2 to find the answer.

Length in inches = (50 cm) / 2.54 = 19.69 inches

Step 5: Round the Answer (Optional)

If your answer includes a large decimal, you may choose to round it to a more manageable number. In this case, we can round the answer to 19.7 inches.

Step 6: Verify the Answer (Optional)

To verify your answer, you can use the reverse conversion to check if it is correct. Convert 19.7 inches back to centimeters using the same formula from step 2.

Length in centimeters = (19.7 in) * 2.54 = 50 cm

The result is the same as the original length we started with, so our answer of 19.7 inches is correct.

Step 7: Practice Conversions

To become more proficient in converting between cm and in, it is helpful to practice with different length values. You can use the same formula and steps outlined above to convert any length in cm to inches and vice versa.

Congratulations, you now know how to convert length from centimeters to inches! Remember to always double check your calculations and units to ensure accuracy.
