Converting Inches to Centimeters

This example problem demonstrates how to convert inches to centimeters.

Problem:

A yardstick is 36 inches. What is this length in centimeters?

Solution:

There are 2.54 centimeters in one inch.
Set up the conversion so the desired unit will be cancelled out. In this case, we want cm to tbe the remaining unit.

length in cm = (length in inches) x (2.54 cm/1 in)
length in cm = (36 x 2.54) cm
length in cm = 91.44 cm

Answer:

A yardstick is 91.44 cm. long.
