## Kilometers to meters conversion factor and formulas

Formula

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

### Multiplication

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

### 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 kilometers to meters, divide kilometers by 0.001.
The formula is expressed as:
km ÷ 0.001 = m

To convert 400 kilometers to meters, multiply 400 kilometers by 1,000.
400 km × 1,000 = 400,000 m

## How long are 400 kilometers?

Real world scale examples to visualize the length of 400 kilometers / 400,000 meters

• 1.16 times the distance from London to Paris (214 mi)
• 98% of the altitude of the International Space Station (254 mi)
• 10% of the distance from New York to Los Angeles (2,445 mi)

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

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.

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).
