## How to Convert Meters to Millimeters

*Example: How many millimeters are equivalent to 11.61 meters?*

As;

1 meters = 1000 millimeters

11.61 meters = Y millimeters

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

Y equals 11.61 times 1000 over 1

(i.e.) Y = 11.61 * 1000 / 1 = 11610 millimeters

Answer is: 11610 millimeters are equivalent to 11.61 meters.
