What is the formula to calculate the consumption of electricity?
Hence, the energy consumption formula or the power consumption formula is given as below: E = P*(t/1000); where E = energy measured in Joules or in kilowatt-hours (kWh), P = power units in watts, and t = time over which the power or energy was consumed.
How do I calculate my daily energy consumption?
Watts Per Day To calculate energy consumption costs, simply multiply the unit’s wattage by the number of hours you use it to find the number of watt-hours consumed each day. For example, let’s say you use a 125 watt television for three hours per day.
How do you calculate the cost of electricity from power and time?
Let’s do the math by hand: power consumption * usage time = power consumed . So we’ll consume 10000 watt hours or 10 kilowatt hours of power every day. The electricity cost is cost = power consumed * energy price .
How do you calculate electricity cost per kWh?
The kilowatt-hour rate is the price of power supplied by your electric provider. To calculate your kilowatt-hour rate, divide your total power bill, minus any taxes, by your total power consumption.
What is the rate of per unit electricity?
6.00 per unit (existing rate of Rs. 5.90) for the first 500 units of monthly consumption and Rs. 7.30 per unit (existing rate of Rs. 7.20) for consumption above 500 units.
How do I calculate electricity consumption per unit?
1 Unit = 1kWh. So the Total kWh = 1000 Watts x 24 Hrs x 30 Days = 720000 … Watts / hour. We want to convert it into electric units, Where 1 Unit = 1kWh….Power Consumption of Typical Home Appliances in Watts.
| Electrical Appliance | Power Wattage in Watts “W” |
|---|---|
| Refrigerator | 250 |
| Electric Heater | 2000 |
| Water Heater | 4000 |
How do you calculate energy consumption from kWh?
Energy Consumption Calculator. Energy consumption calculator. kWh calculator. 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)
How do I calculate the cost of an energy efficient appliance?

How do you calculate the cost of electricity?
Electricity bill cost calculator. Electricity usage consumption calculator. 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)
