Millimeters to Meters (mm to m) Converter
1 millimeter (mm) = 0.001 meters (m). To convert millimeters to meters, multiply by 0.001: 297 mm × 0.001 = 0.297 m. Also searched as millimetres to metres.
Quick facts
- 1 mm = 0.001 m
- 1 m = 1,000 mm
- Formula: m = mm × 0.001
- Quick estimate: multiply by about 0.001
How to convert millimeters to meters
- Take the value in millimeters.
- Multiply it by 0.001 (the number of meters in one millimeter).
- Round the result to the precision you need.
Worked example (the long side of an A4 sheet): 297 mm × 0.001 = 0.297 m.
To convert meters back to millimeters, multiply by 1,000, or divide by 0.001.
