Comment convertir puissance électrique en watts (W) to energy en kilowatt-heure (kWh).
You can calculate kilowatt-hour from watts and hours. You can't convert watt to kilowatt-hour unit sence watt and kilowatt-hour unit represent different quantities.
The energy E en kilowatt-heure (kWh) is equal to the power P in watts (W), times the time period t in hours (hr) divided by 1000:
E(kWh) = P(W) × t(hr) / 1000
Donc
kilowatt-heure = watt × heure / 1000
ou
kWh = W × hr / 1000
What is the energy consumption en watt-hour when the power consumption is 5000 watts fou time duration of 3 hours
E = 5000W × 3h / 1000 = 15 kWh
