Step 1: Understand the Units of Length

Before starting the conversion, it is essential to have a good understanding of the units involved. In this case, we are converting from centimeters (cm) to inches (in).

Step 2: Write Down the Given Measurement

Write down the given measurement in centimeters. In this example, the given measurement is 12cm.

Step 3: Set Up the Conversion Formula

To convert from cm to in, we will use the conversion factor of 1 in = 2.54 cm. This means that 1 inch is equal to 2.54 centimeters.

Step 4: Set Up the Conversion Equation

Using the conversion factor, we can set up the equation as follows:

12cm x (1 in/2.54 cm)

Step 5: Cancel Out the Common Unit

In this case, the common unit is cm. When we multiply 12cm by (1 in/2.54 cm), the cm unit will cancel out, leaving us with only the desired unit, which is in.

Step 6: Solve the Equation

To solve the equation, we simply multiply 12 by 1 and then divide the result by 2.54. This can be done using a calculator or manually.

(12 x 1)/2.54 = 4.7244094488 in

Step 7: Round the Answer

The answer, in this case, is a decimal number. For practical purposes, we can round it to two decimal places, which gives us 4.72 in.

Step 8: Write the Final Answer

The final step is to write the converted measurement with the appropriate unit. Therefore, we can say that 12cm is equal to 4.72 inches.

Final Answer: 12cm = 4.72 inches.

Congratulations, you have successfully converted 12cm to inches!
