# Which of the following units are units of length?

The most common units that we use to measure length in the metric system are the millimeter, centimeter, meter, and kilometer. The millimeter is the smallest commonly used unit in the metric system.

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity.

Also Know, what are the units for area? In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares.
