This system is basically built upon seven base units which are Metre Kilogram Ampere Kelvin Second Candela and Mole. Base units can be put together to derive units of measurement for other quantities. These other units are called SI derived units for example the SI derived unit of area is square metre m 2 and of density is kilograms per cubic metre kgm 3.
James Watt 17361819 was a Scottish inventor and mechanical engineer who developed a more efficient steam engine. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units. They are either dimensionless or can be expressed as a product of one or more of the base units possibly scaled by an appropriate power of exponentiation.
