## Meters to kilometers conversion factor and formulas

Formula

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

### Division

To convert from meters to kilometers, divide meters by 1,000.
The formula is expressed as:
m ÷ 1,000 = km

### Multiplication

Alternatively we can multiply 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 kilometers, multiply meters by 0.001.
The formula is expressed as:
m × 0.001 = km

A conversion from meters to kilometers 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 kilometer is officially defined as being equal to 1,000 meters. It is commonly used as measurement for geographic distances in similar circumstances where a mile would be used in the U.S. Internationally it is spelled 'kilometre' whereas the U.S. spells it 'kilometer'. The symbol for a kilometer is km however k is sometimes used.
