## Definition: Zettajoule

The SI prefix "zetta" represents a factor of 1021, or in exponential notation, 1E21.

So 1 zettajoule = 1021 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: Therm

The therm (symbol, thm) is a non-SI unit of heat energy equal to 100000 British thermal units (Btu[1]). It is approximately the energy equivalent of burning 100 cubic feet (2.83 cubic metres) – often referred to as 1 CCF – of natural gas.

The therm (EC) is often used by engineers in the US.
