Rational scale

Abbreviation None
Synonym Unitary ratio scale, ratio scale
Definition Rational scale (property) has a magnitude and can be divided by another property
Scope The value set is a set of numerical values. There is an absolute zero point.
Description

The numerical values of a quantity can be added, subtracted, multiplied and divided.

Note 1: Results have ISQ dimensions and measurement units.

Value set 0–∞
