## How to Convert Miles to Inches

*Example: How many inches are equivalent to 90.78 miles?*

As;

1 miles = 63360 inches

90.78 miles = Y inches

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

Y equals 90.78 times 63360 over 1

(i.e.) Y = 90.78 * 63360 / 1 = 5751820.8 inches

Answer is: 5751820.8 inches are equivalent to 90.78 miles.
