How are is measured?
Are, unit of area in the metric system, equal to 100 square metres and the equivalent of 0.0247 acre. Its multiple, the hectare (equal to 100 ares), is the principal unit of land measurement for most of the world. The are was the basic unit of area when the metric system was first decreed in France in 1795.
How do you measure in units?
We usually write units just using their abbrevations.
- Example: km for kilometer.
- Example: m/s (or m s-1) for meter per second. m/s is a unit of speed.
- Example: kg/m3 (or kg m-3) for kilogram per cubic meter. kg/m3 is a unit of density: how much mass per unit of volume.

Who found standard unit?
In the middle of the 19th century, James Clerk Maxwell conceived a coherent system where a small number of units of measure were defined as base units, and all other units of measure, called derived units, were defined in terms of the base units. Maxwell proposed three base units for length, mass and time.
