To convert a megajoule unit of measure to a joule unit of measure, multiply the energy by the conversion ratio. The energy in joules equals megajoules multiplied by 1,000,000.
The millijoule (mJ) corresponds to one thousandth (10−3) of a joule.
The unit number Joule 1,000,000.00 J is converted to 1 MJ, a megajoule. It is the SAME energy value of 1 megajoule, but in the alternative energy unit joule.
One megajoule contains 1,000 kilojoules, which is why we use this value in the formula above. Megajoules and kilojoules are both units of measurement of energy.
Therefore, a KiloJoule (kJ) corresponds to 1000 Joules and a MegaJoule (MJ) corresponds to 1,000,000 Joules.
One megajoule equals 1,000,000 joules, which is the energy equivalent to the force on an object of one newton at a distance of one meter. The megajoule is a multiple of the joule, the SI derived unit of energy. In the metric system, “mega” is the prefix for 106.
kJ↔MJ 1 MJ = 1000 kJ.
To convert a megajoule measurement to a kilowatt hour measurement, multiply the energy by the conversion ratio. Energy in kilowatt hours equals megajoules multiplied by 0.277778.
mJ/kg↔J/kg 1 J/kg = 1000 mJ/kg.
