Verified step by step guidance1
Understand that the meter is a fundamental unit used in the International System of Units (SI).
Recall that SI base units are defined for different physical quantities such as length, mass, time, and electric current.
Identify the physical quantity that the meter measures, which is length.
Recognize that the meter is the SI base unit for length, not for electric current, mass, or time.
Conclude that the correct description of the meter is that it is the SI base unit of length.
