## Meters to millimeters conversion factor and formulas

Formula

The conversion factor between meters and millimeters is 1,000. This represents the ratio of millimeters per one meter. To calculate the value in millimeters, we can either multiply by the conversion factor or divide by its inverse.

### Multiplication

To convert from meters to millimeters, multiply meters by 1,000.
The formula is expressed as:
m × 1,000 = mm

### Division

Alternatively we can divide by the inverse conversion factor to get the same result.
The inverse of 1,000 is 1/1,000 or 0.001. To convert from meters to millimeters, divide meters by 0.001.
The formula is expressed as:
m ÷ 0.001 = mm

A conversion from meters to millimeters are units within in the metric (SI) or SI compatible systems.

SI Unit

The meter is the primary unit for measurement of length within the metric (SI) system of measure. It is officially defined as the distance which light travels in 1/299,792,458th of a second in a vacuum. Internationally the meter is usually spelled 'metre', however the prevalent spelling in the United States is 'meter'. Its symbol is the lower case letter m. The meter is the base unit for deriving all other SI units of length eg. kilometer (1,000 meters).

SI Unit

Within the SI (metric) system of measurement, the millimeter is officially defined as one thousandth (1/1,000) of a meter. It is commonly used when measuring very short lengths. Internationally it is spelled 'millimetre' whereas the U.S. spells it 'millimeter'. The symbol for millimeters is mm.
