Convert Meters to millimeters
1 meter = 1,000 millimeters · mm = m × 1,000
When you need this conversion
This conversion goes from meters, the SI base unit of length used for rooms, buildings, and sports distances, to millimeters, the metric unit used for hardware, engineering drawings, and anything needing sub-centimeter precision. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.
