Relation between SI unit and Commercial Unit of energy is 1 kWh = 3.6 * 10^6 J

Explanation:

Commercial unit of energy is kiloWatt-hour (kWh) and SI unit of energy is Joule (J). 1 kiloWatt hour = 1000W * 1h

Now, 1 W = 1 J/sec

⇒ 1 kiloWatt hour = 1000 * 60 * 60 (Since 1 h = 60 * 60 s)

⇒ 1 kWh = 3.6 * 10^6 J
