## How to Convert Meters to Kilometers

*Example: How many kilometers are equivalent to 51.38 meters?*

As;

1 meters = 0.001 kilometers

51.38 meters = Y kilometers

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

Y equals 51.38 times 0.001 over 1

(i.e.) Y = 51.38 * 0.001 / 1 = 0.05138 kilometers

Answer is: 0.05138 kilometers are equivalent to 51.38 meters.
