  2. A derived unit in the SI system is formed by combining base units according to algebraic relationships. Examples: Newton (N): SI unit of force, derived as kg\cdotpm/s^2. Derived units are not fundamental but rely on the seven SI base units (meter, kilogram, second, etc.). For more please visit here:Read more
