I didn't - but the history of standard measurement units goes back centuries.
The drive to make all countries uses the SI units for trade, science and engineering is very recent and continuing.
A parallel development is that of standard screw-threads and fastenings dimensions, pioneered particularly by the 19C British engineer Sir Joseph Whitworth.
There are exactley 7 units of measurements
SI units
If you mean the units, the most commonly used units are degrees, and radians.
Time
In square units of measurements
SI units are defined for physical measurements, like measurements of mass, length, etc. - there are no specific SI units for plain numbers.SI units are defined for physical measurements, like measurements of mass, length, etc. - there are no specific SI units for plain numbers.SI units are defined for physical measurements, like measurements of mass, length, etc. - there are no specific SI units for plain numbers.SI units are defined for physical measurements, like measurements of mass, length, etc. - there are no specific SI units for plain numbers.
Metric units of measurement are more fun to say.
To do math.

Consistent
The world system of measurements units is based on the metric system (SI).
scientist behind the units of measurement
International System of Measurements.
By unit of length and mass and conversion ,we can say that units of measurements in length are meters ,cm ,dm ,dam ,hm.
All ratio measurements must be in the same units before simplifying
Measurements are made in units. The specific units that you would use depend upon what it is that you wish to measure. Practically anything can be measured.
