All measurements must have a value and a unit. For example 3 (value) cm (unit). Measurement assigns a numerical value and unit to the characteristics of an object/event, for comparison with other objects or events.

Answer:

A number and its unit.

Explanation:

Measurement may be defined as the assignment of the any number with the characteristics of any event or objects. The nominal properties of object are not included in the measurement.

The measurement must include a number and the measurable unit. For example : 5 m consists of both the number 5 and the measurable unit present in meters.

Thus, the answer is a number and its unit.
