Question

What is the SI equivalent of the commercial unit of energy (1kWh)?​

Answer 1

Answer:

3.6x10⁶ J

Explanation:

1 hr = 3600s = 3.6x 1000 s

1 kW = 1000J/s

Therefore,

1 kWh = 1000 x 3.6x 1000 J = 3.6x10⁶ J

Answer 2

Answer:

Commercial Unit of Energy. The SI unit joule is too small to express very large quantities of energy. Hence we use a bigger unit called kilowatt hour (kWh) to express energy. 1kWh is the amount of energy consumed by an electrical gadget in one hour at the rate of 1000 J/s or 1kW.

Commercial Unit Of Energy =kWh

            SI Unit Of Energy = Joule (J)

1kWh=1kW×1h

=>1000W ×3600s

1 watt - second = 1 joule

1kWh=3600000J

Explanation:

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.
