Explain the difference between SI base units and derived units Give an example of each?

Answer 1

Derived units are units built up from SI base units. It has been found that relatively few base units are required.

Typical derived units are m/sec (metres per second), sometimes written m.sec-1 for speed and joules/sec, sometimes written joules.sec-1 for power. Although the latter unit is a derived unit, it has its own name, the watt, for convenience. (Nonetheless, the people who govern the business of defining units have been scrupulous in defining it in terms of base units because it's possible.) New base units are defined when phenomena are encountered which simply cannot be measured in terms of existing base units or units derived from them.

Answer 2

A SI base unit is a direct measurement unit for a physical entity, an example of which is kilogram. A derived unit is determined by a physical equation with the base units, an example of which is meter per second.

Answer 3

There are several SI base units, and many more derived units, which are combinations of other units. For example, meter and second are base units, meter/second (for speed or velocity) is a derived unit. For more details, see these links:

Answer 4

SI base units are independent units that are used to define other units, while derived units are combinations of base units. For example, the meter is a base unit used to measure distance (m), while the newton is a derived unit that combines kilogram, meter, and second to measure force (N).

Answer 5

Both can be a measurement unit for length, mass and time.
