You can do the reverse unit conversion from millimegajoule to hectojoule, or enter any two units below:
The SI prefix "hecto" represents a factor of 102, or in exponential notation, 1E2.
So 1 hectojoule = 102 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).
The SI prefix "milli" represents a factor of 10-3, or in exponential notation, 1E-3.
So 1 millimegajoule = 10-3 megajoules.
