›› Definition: Kilojoule

The SI prefix "kilo" represents a factor of 103, or in exponential notation, 1E3.

So 1 kilojoule = 103 joules.

The definition of a joule is as follows:

The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889).

›› Definition: Calorie

15 C calorie: the amount of energy required to warm 1 g of air-free water from 14.5 C to 15.5 C at a constant pressure of 101.325 kPa (1 atm). Experimental values of this calorie ranged from 4.1852 J to 4.1858 J. The CIPM in 1950 published a mean experimental value of 4.1855 J, noting an uncertainty of 0.0005 J.
