Rechner für Stromkosten und Berechnungsanleitung.
The energy E in kilowatt-hours (kWh) per day is equal to the power P in Watt (W) times number of usage hours per day t divided by 1000 watts per kilowatt:
E(kWh/Tag) = P(W) × t(h/Tag) / 1000(W/kW)
The energy cost per day in dollars is equal to the energy consumption E in kWh per day times the energy cost of 1 kWh in Cents/kWh divided by 100 cents per dollar:
Kosten($/Tag) = E(kWh/Tag) × Kosten(Cent/kWh) / 100(Cent/$)
