Efficiency. It's easier to say ' 10 kilometers' than it is to say '10,000 meters.'
there are many units for measurements .three measurements are bigger than a kilometer are miles , light years and megameters .
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.
There are 7 fundamental units in S.I system .Thus ,for unit of length and mass and conversion ,the relations are given .By the conversion table :We can say that miles,light years and astronomical units are bigger than kilometers .
Metric units of measurement are more fun to say.
To do math.
There are exactley 7 units of measurements

The world system of measurements units is based on the metric system (SI).

All ratio measurements must be in the same units before simplifying
