## How to Convert Millimeters to Meters

*Example: How many meters are equivalent to 28.74 millimeters?*

As;

1 millimeters = 0.001 meters

28.74 millimeters = Y meters

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

Y equals 28.74 times 0.001 over 1

(i.e.) Y = 28.74 * 0.001 / 1 = 0.02874 meters

Answer is: 0.02874 meters are equivalent to 28.74 millimeters.
