# Megajoule

## Definition - What does Megajoule mean?

Megajoule is a unit of energy which is equivalent to 1 million Joules (10^6 Joules). It is one of the multiples of Joule and is represented by the symbol MJ. One Megajoule is also equivalent to kinetic energy of a vehicle moving at a speed of 99.42 mph considering the weight of vehicle is one metric ton. Joule is treated as equivalent to one watt of power dissipated for one second and thus, one Megajoule is equal to 10^6 Watt-sec.
