## How to Convert Miles to Inches

*Example: How many inches are equivalent to 67.8 miles?*

As;

1 miles = 63360 inches

67.8 miles = Y inches

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

Y equals 67.8 times 63360 over 1

(i.e.) Y = 67.8 * 63360 / 1 = 4295808 inches

Answer is: 4295808 inches are equivalent to 67.8 miles.
