REFERENCE / WHAT IS A UNIT?
A shared language
for quantity.
A unit is an agreed standard used to describe a measurable quantity. Distance, mass, temperature, time, and other quantities become useful when expressed as a number multiplied by a known unit.
Different cultures developed different measurement systems. Today, the International System of Units (SI) is the global standard, while US customary and Imperial units remain common in parts of the world.
Convertor4U makes those systems easier to understand and translate—using exact definitions for fixed units and dated reference data for currencies.
