# unit-free measure meaning

[Economics]

A variable which is a pure number, independent of the units in which variables such as price or quantity are measured. Examples of unit-free measures are percentages, market shares, and elasticity. Interest rates and growth rates are not unit-free measures, as while they are independent of the units in which prices and quantities are measured, they do depend on the units used to measure time.
