# Millimeters to meters

**1 millimeter in meters: 1 mm = 0.001 m**

m = mm × 0.001

To convert millimeters to meters, multiply by 0.001. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is m = mm × 0.001. Both units measure length, so the conversion is a fixed factor that never changes.

## Common questions

### How many meters are in one millimeter?

One millimeter equals 0.001 meters. m = mm × 0.001.

### How do you convert millimeters to meters?

Use m = mm × 0.001. So 10 mm is 0.01 m.

### How many millimeters are in one meter?

One meter equals 1,000 millimeters, which is the reverse of the conversion above.
