Each value measured in nature has a number value, called its magnitude, and a dimension, or unit.

Explanation:

Measurement is a basic process of science that is based on comparing a selected unit of measure with the object or phenomenon whose physical magnitude you want to measure, to find out how many times the unit is contained in that magnitude.

Therefore, each value measured in nature has a number value, called its magnitude, and a dimension, or unit.
