**Meter** (abbreviation: **m**): is the base unit of length in the International System of Units (SI). The metre is the length of the path travelled by light in a vacuum within 1/299792458 seconds.

## How to Convert Kilometers to Meters

*Example: How many meters are equivalent to 21.26 kilometers?*

As;

1 kilometers = 1000 meters

21.26 kilometers = Y meters

Assuming Y is the answer, and by criss-cross principle;

Y equals 21.26 times 1000 over 1

(i.e.) Y = 21.26 * 1000 / 1 = 21260 meters

Answer is: 21260 meters are equivalent to 21.26 kilometers.
