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:
A: 1 unit equals 1 kWh (kilowatt-hour) of electricity consumption in your electricity bill calculator. When your meter shows 300 units consumed, that represents 300 kilowatt-hours of energy usage that determines your monthly electricity cost.
A: To calculate electricity consumption in units, multiply appliance power (watts) × usage hours ÷ 1000 = kWh units consumed. For example, a 1000W appliance running 5 hours daily consumes 5 kWh (5 units) per day using our consumption calculator.
A: The best energy consumption calculator multiplies device wattage by operating hours and divides by 1000 to get kWh. Our kWh calculator automatically converts watts to kilowatt-hours, helping you estimate daily, monthly, and annual electricity usage accurately.
A: Enter appliance power rating (watts), daily usage hours, and electricity rate (₹/kWh) into our household calculator. The tool calculates total kWh consumption and monthly electricity cost for all home appliances including AC, refrigerator, TV, and lights.
A: Average electricity consumption in India ranges from 150-300 units (kWh) monthly for households, costing ₹6-9 per unit for residential consumers. Our India-specific calculator includes state-wise tariff rates for accurate electricity bill estimation and energy cost planning.
A: Multiply total kWh consumption by your electricity tariff rate (₹/kWh) to calculate monthly electricity cost. Our electricity cost calculator automatically applies slab rates, fixed charges, and taxes for precise bill estimation and energy expense management.
