You can do the reverse unit conversion from millijoule to hectojoule, or enter any two units below:

hectojoule to decajoule

hectojoule to ton

hectojoule to femtojoule

hectojoule to terajoule

hectojoule to zettajoule

hectojoule to kilogram-force meter

hectojoule to erg

hectojoule to dekatherm

hectojoule to gigajoule

hectojoule to kiloelectron volt

The SI prefix "hecto" represents a factor of
10^{2}, or in exponential notation, 1E2.

So 1 hectojoule = 10^{2} 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 millijoule = 10^{-3} 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).
