**Candle:** Candela is defined as the luminous intensity of 1 / 600,000 of a square meter of the cavity at a platinum freezing temperature (2042 ok). Neo The mole is defined as the amount of substance in a system that contains as many Elementary entities such as atoms are in 0.012 kilograms of carbon-12.

**Joule:** Joule is defined as the energy expended to move an object one kg across a distance of one meter A joule equals 0.7376 foot-pounds of strength and 0.2388 calories.

**Watt:** Watt is defined as the “work rate”. One watt = 1 joule / second One watt equals 0.7376 ft-lbs / s or equals 1 / 745.7 horsepower. decimal system The SI system uses the decimal system to relate the largest and smallest units to the base units. That use prefixes to indicate the different powers of 10.
