About these units
Meter (m)
- Definition
- The meter (m) is the SI base unit of length, defined as the distance light travels in a vacuum in 1/299,792,458 of a second.
- History
- Introduced in France in 1793 as one ten-millionth of the distance from the equator to the North Pole, it was later fixed by a platinum bar and, since 1983, by the speed of light.
- Current use
- The meter is the standard unit of length in nearly every country and underpins science, engineering, construction, and sport worldwide.
Light Year (ly)
- Definition
- A light-year (ly) is the distance light travels in one year in a vacuum, about 9.46 trillion kilometers.
- History
- The concept arose in the 19th century as astronomers sought an intuitive way to express the vast distances between stars.
- Current use
- Light-years express distances to stars and galaxies in astronomy and popular science.
