## How to Convert Meters to Millimeters

*Example: How many millimeters are equivalent to 62.46 meters?*

As;

1 meters = 1000 millimeters

62.46 meters = Y millimeters

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

Y equals 62.46 times 1000 over 1

(i.e.) Y = 62.46 * 1000 / 1 = 62460 millimeters

Answer is: 62460 millimeters are equivalent to 62.46 meters.
