Because otherwise you'll be embarrassed a lot when your 75 inch pants keep falling off your 75 cm waist.
Metric units of measurement are more fun to say.
They use scientific notation for very large or very small measurements
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.
So that we all understand what we are doing.
Metric measurements use powers of 10 to create larger and smaller units.

mm (millimeters)
Sort of. US measurements are now for the most part defined in terms of SI units. Also, a few SI units such as "seconds" are used directly.
If they are sensible, they will use those units defined and agreed by the International Standards Organization (ISO), as these will be universally understood and normally are required to be used in scientific publications.
The same units that you use for length and distance. For example, the SI unit would be the meter.
they are easy to use
SI units such as kilograms, meters, liters etc
