How many kilojoules in 1 megajoules? The answer is 1000. We assume you are converting between kilojoule and megajoule. You can view more details on each measurement unit: kilojoules or megajoules. The SI derived unit for energy is the joule. 1 joule is equal to 0.001 kilojoules, or 1.0E-6 megajoules
Those units are unrelated, and uncompatible - can't be converted. Grams / hour has units of mass / time. Joules or megajoules is a unit of energy.
35 MegaJoules
It depends on the efficiency of the appliance. If an electric motor has an efficiency of 0.7, then for every 1000 megajoules, 30 megajoules will be wasted as useless heat or sound or other useless energy form.
1 kg alcohol is 29.7 MJ (megajoules).
The energy content of coal can vary, but on average, one kilogram of coal contains around 24 megajoules (MJ) of energy.
