1 Wh ≈ 3.6 kJ
Precision changes displayed rounding, not calculation accuracy.
kJ = Wh × 3.6kJ = Wh × 3.6
Multiply the Wh reading by 3.6.
1 Wh ≈ 3.6 kJ
1 × 3.6 ≈ 3.6
1000 Wh ≈ 3600 kJ
1000 × 3.6 ≈ 3600
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.
