About the kilometer and the meter
The meter
The meter (m) is the SI base unit of length. Defined since 2019 as the distance light travels in vacuum in exactly 1/299,792,458 of a second, the meter is the reference all other length units derive from. It is the standard unit for room dimensions, sports fields, and short-to-mid distances in most of the world.
