## How to Convert Kilometers to Inches

*Example: How many inches are equivalent to 9.17 kilometers?*

As;

1 kilometers = 39370.08 inches

9.17 kilometers = Y inches

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

Y equals 9.17 times 39370.08 over 1

(i.e.) Y = 9.17 * 39370.08 / 1 = 361023.6336 inches

Answer is: 361023.6336 inches are equivalent to 9.17 kilometers.
