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
Metric units of measurement are more fun to say.
1-200 in SI units typically refers to the range of values for measurements such as length, mass, time, etc., which are expressed using the International System of Units (SI). For example, 1-200 meters for length, 1-200 grams for mass, and 1-200 seconds for time.
To do math.

The system of units used for measurements in chemistry is called the International System of Units (SI). It is a globally recognized system that provides a consistent set of units for measuring physical quantities.

scientist behind the units of measurement
There are 1000 measurements in a kilogram.
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.
When using shortening for cooking or when baking there are standard units of measurements. The units of measurements are cups, tablespoon and teaspoons.
