derived units come from basic units such as length, time, electrical current.
AnswerIn SI, Derived Units are any units that are not Base Units. There are seven Base Units, from which all Derived Units are formed. For example, a coulomb (derived unit) is equal to an ampere second (both Base Units).
Those are called derived units.
Derived units are units formed by combining base units through mathematical operations, such as area (square meters). Supplementary units are units used alongside base units to form the complete set of units in a system, such as the radian for angles in the International System of Units.
Because they are based on - i.e. "derived from" - other units.
derived units
Derived units is obtained from a combination of fundamental units. Derived unit is a cubic centimeter or a cube that is a centimeter on each side.

Derived units
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
The fundamental units are based on specific standards for each unit. Derived units result from manipulating the fundamental units. For example, the SI unit for distance or length is the meter, and the SI unit for time is the second. If you divide meters by seconds, you get m/s, a derived unit for speed or velocity.
They can be classified into fundamental units and derived units.
Derived units
A derived unit in the International System of Units (SI) is a unit derived from the base units through multiplication, division, or exponentiation. These derived units are obtained by combining base units with a specific mathematical formula to represent complex physical quantities.
