All other units are made by mathematically combining the fundamental units. These are called derived units.
Explanation:
In physics, a physical quantity is any physical property that can be quantified, that is, be measured using numbers. Examples of physical quantities are mass, amount of substance, length, time, temperature, electric current, light intensity, force, velocity, density, and many others.
A physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as the combination of a numerical value and a unit. For example, the physical quantity mass can be quantified as n kg, where n is the numerical value and kg is the unit.
