To quantify something is to work out its value or size and express that as a number or an amount. You quantify rainfall in , or quantify a company's loss in dollars. The word is at home in science, business, and reports. People also stretch it to things that do not sit still on a scale — quantifying happiness, or quantifying how much someone cares — and that use is common, though actually a bit hopeful, because the number is only as good as the measuring stick. A philosopher, Sir William Hamilton, brought the Latin word into English for logic, where it meant saying whether a statement was about all or some.
From the word’s history
