## Fundamental and Derived quantities,units and dimensions

Fundamental and Derived quantities,units and dimensions Physical quantities have no meaning, unless is measured quantified and give a unit. Therefore we need number or quantity and unit of measurement to specify physical quantities. There two type of physical quantities, Fundamental and derived quantities. Among the fundamental quantities we have three most important, there LENGTH, MASS, …

## How to take Measurement of length, mass and volume

Measurement of length A length can something  be measured by using meter rule, caliper, venire caliper, and micro screw gauge. The instrument for measurement of length depends on how large or small the length is. If the length is very long like foot ball field, you use tape; a shorter distance like your reading table …
