1 kWh ≈ 3600 kJ
Precision changes displayed rounding, not calculation accuracy.
kJ = kWh × 3600kJ = kWh × 3600
Multiply the kWh reading by 3600.
1 kWh ≈ 3600 kJ
1 × 3600 ≈ 3600
10 kWh ≈ 36000 kJ
10 × 3600 ≈ 36000
No. A watt-hour measures energy; a watt measures power. One watt-hour is the energy transferred at one watt for one hour, equal to 3,600 joules.
