## How to Convert Miles to Kilometers

*Example: How many kilometers are equivalent to 41.2 miles?*

As;

1 miles = 1.609344 kilometers

41.2 miles = Y kilometers

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

Y equals 41.2 times 1.609344 over 1

(i.e.) Y = 41.2 * 1.609344 / 1 = 66.3049728 kilometers

Answer is: 66.3049728 kilometers are equivalent to 41.2 miles.
