What is a Unit of Measurement?
Put simply, a unit of measurement is a quantity that has been defined. Sometimes this is defined by historic tradition and other times by law. Quantities of the unit are then expressed as a multiple of it.
Throughout human history, we have developed and used a number of different unit systems in regions and cultures all across the globe. There is now a global standard of unit measurement, called the International System of Units (SI). This is a modern form of the metric system. SI is still not fully adopted and some parts of the world use other systems of measurement.
