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
