Energy Cost Calculation
Energy Consumption Calculation
The energy E in kilowatt-hours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt:
E(kWh/day) = P(W) × t(h/day) / 1000(W/kW)
Energy Cost Calculation
Calculating the daily energy expense in dollars requires multiplying the daily energy consumption (E) in kilowatt-hours (kWh) by the cost of one kWh in cents/kWh, and then dividing the result by 100 cents to convert it to dollars:
Cost($/day) = E(kWh/day) × Cost(cent/kWh) / 100(cent/$)
