## How to Convert Centimeters to Inches

*Example: How many inches are equivalent to 49.57 centimeters?*

As;

1 centimeters = 0.393701 inches

49.57 centimeters = Y inches

Assuming Y is the answer, and by criss-cross principle;

Y equals 49.57 times 0.393701 over 1

(i.e.) Y = 49.57 * 0.393701 / 1 = 19.51575857 inches

Answer is: 19.51575857 inches are equivalent to 49.57 centimeters.
