1 kWh ≈ 1000 Wh
Precision changes displayed rounding, not calculation accuracy.
Wh = kWh × 1000Wh = kWh × 1000
Multiply the kWh reading by 1000.
1 kWh ≈ 1000 Wh
1 × 1000 ≈ 1000
10 kWh ≈ 10000 Wh
10 × 1000 ≈ 10000
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.
