Millimeters to Meters Converter
1 millimeter = 0.001 meters
1 millimeter equals 0.001 meters
How to convert millimeters to meters
Feet, inches, yards and miles use the international foot (0.3048 m). Older US survey-foot records use a different definition; check the survey document before applying these factors.
m = mm × 0.001One millimeter is 0.001 meters, so a single multiplication converts any value.
0.01 m = 10 × 0.001Millimeters to meters conversion table

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
