Question

prove it 1 kwh= 3.6 MJ.​

Answer 1

Explanation:

The Joule (J) is the unit of measure for energy or work. The quantity of energy to do an amount of work is the same.

The Watt (W) is the unit of measure for power.

power = work / time = energy / time

So, work (or energy) = power x time

1 kWh = 1000 Wh = 1000 W x 3600 second = 3.6 MWs = 3.6 MJ
