Measure

That by which extent or dimension is ascertained, either length, breadth, thickness, capacity or amount. Webster. The rule by which anything is adjusted or proportioned.

— Measure of damages. The rule, or rather the system of rules, governing the adjustment or apportionment of damages as a compensation for injuries in actions at law.

— Measure of value. In the ordinary sense of the word, "measure" would mean something by comparison with which we may ascertain what is the value of anything. When we consider, further, that value itself is relative, and that two things are necessary to constitute it, independently of the third thing, which is to measure it, we may define a "measure of value" to be something by comparing with which any two other things we may infer their value in relation to one another. 2 Mill, Pol. Econ. 101.
