Answer:
The commercial unit of energy is 1 kWh. One kilowatt-hour is defined as the amount of energy that is consumed by a device in one working hour at a constant rate of one kilowatt.
The SI unit of energy is Joule.
Therefore, the relationship between commercial and SI unit of energy is:
1 kWh = 1kW x 1h = 1000W x 1h = 1000(J/s) x 3600 s = 3.6 x106 J
Hope this helps you stay safe
