Type a value in MJ to get it in J instantly.
100,000,000J
That's 12× as much energy as a day of eating, while charging an electric car is 2.2× more. That could lift a one-tonne car 10,200 m into the air.
What it means
What could that energy do?
The hill climb ignores friction and assumes a 1,000 kg car. Food calories on labels are kilocalories.
The math
How to convert MJ to J
To convert megajoules to joules, multiply by 1,000,000.
Example: 100 MJ × 1,000,000 = 100,000,000 J.
In the other direction, 1 J = 1×10⁻⁶ MJ.

Megajoules (MJ)
A megajoule is a million joules, about the energy in a quarter of a chocolate bar or a fifth of a kilowatt-hour.
Joules (J)
The joule is the SI unit of energy: the work done pushing with one newton over one meter. Lifting an apple a meter takes about one joule.
