전기 에너지 비용 계산기 및 계산 방법.
The energy E in kilowatt-hours (kWh) per day is equal to the power P in 와트 (W) times number of usage hours per day t divided by 1000 watts per kilowatt:
E(kW시간/일) = P(W) × t(시간/일) / 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 센트s/kWh divided by 100 cents per dollar:
비용($/일) = E(kW시간/일) × 비용(센트/kWh) / 100(센트/$)
