The base unit of the metric system for length is the meter. It is defined as the distance traveled by light in a vacuum in 1/299,792,458 of a second. The meter is used to measure small distances, such as the length of a pencil, as well as larger distances, such as the height of a building or the length of a road. It is a fundamental unit of measurement in the metric system and is widely used in scientific and everyday applications.
