Converting the other way: meters to millimeters
millimeters = meters × 1,000. So 0.12 meters is back to 120 millimeters; one meter is 1,000 millimeters. See the meters to millimeters table.
Quick estimate in your head
For a rough answer, multiply by about 0.001: 120 × 0.001 ≈ 0.12 m, against the exact 0.12 m (0.0% out). Good enough to check that a calculated result is sensible.
Common mistakes
The usual slip is using the factor the wrong way round. A millimeter is smaller than a meter, so the number of meters must come out smaller than the number of millimeters. If your answer goes the other way, divide instead of multiplying.
About the units
Millimeter (mm) and meter (m) are both units of length. One millimeter equals 0.001 meters, and one meter equals 1,000 millimeters. Results on this page are rounded for display; the conversion itself uses the exact definitions.
Length conversions come up in DIY and building plans, running and cycling distances, maps, clothing sizes and travel between countries that use metric and imperial units.
