Meter (m) – Unit of Length
The meter (m) is the fundamental unit of length in the metric system. It is used worldwide in science, engineering, construction, and everyday measurements.
What Is a Meter?
A meter is the base unit of length in the International System of Units (SI). It is abbreviated as m.
One meter is officially defined as the distance light travels in vacuum in 1/299,792,458 of a second.
History of the Meter
The meter was originally defined in the late 18th century as one ten-millionth of the distance from the equator to the North Pole along a meridian.
Over time, the definition evolved for greater precision, leading to the modern physics-based definition used today.
