ratio scale

a measurement scale having a true zero (i.e., zero on the scale indicates an absence of the measured attribute) and a constant ratio of values. Thus, on a ratio scale an increase from 3 to 4 (for example) is the same as an increase from 7 to 8. The existence of a true zero point is what distinguishes a ratio scale from an interval scale.
