How to Convert Kilometers to Meters

Tape measures can be used to measure units of length, and a calculator can be used to convert to another unit

To convert a kilometer measurement to a meter measurement, multiply the length by the conversion ratio. One kilometer is equal to 1,000 meters, so use this simple formula to convert:

meters = kilometers × 1,000

The length in meters is equal to the kilometers multiplied by 1,000.

For example, here's how to convert 5 kilometers to meters using the formula above.
5 km = (5 × 1,000) = 5,000 m

Kilometers and meters are both units used to measure length. Keep reading to learn more about each unit of measure.

Kilometers

One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.[1]

The kilometer, or kilometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "kilo" is the prefix for 103. Kilometers can be abbreviated as km, for example 1 kilometer can be written as 1 km.

Meters

The meter is defined as the distance light travels in 1/299,792,458 of a second in a vacuum, according to the most recent 1983 definition. One meter is equal to 100 centimeters or 39.37 inches.

The meter, or metre, is the SI base unit for length in the metric system. Meters can be abbreviated as m, for example 1 meter can be written as 1 m.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.

If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
