Other forms: measurements
A measurement is the exact size or amount arrived at by careful checking. A number, and the unit that goes with it.
It names both the act and the result, so you take a measurement and you write the measurement down. Dressmaking and building use the plural constantly, since taking somebody's measurements means recording chest, waist and inside leg. Science divides it further, distinguishing the measurement from the thing measured. The verb is measure, and a measure can also be a step taken, which is a quite separate sense worth keeping apart.
1nounmeasurementThe size, amount or degree of something found by measuring.
“He wrote the measurement on the back of his hand.”
2nounactThe act of measuring.
“Accurate measurement is the whole difficulty.”
Too few real examples of this word to estimate which sense is commonest.
