What is a unit of electricity?
A unit of electricity is one kilowatt-hour (kWh). It means using 1,000 watts of power for one hour. Your electricity bill is typically based on the total kWh consumed.
How do I calculate electricity units from watts?
Multiply the wattage by the hours used, then divide by 1000. Example: a 500W appliance used for 5 hours consumes 2.5 kWh, or 2.5 units.
What is the difference between connected load and running load?
Connected load is the total wattage of all installed appliances. Running load is the wattage of appliances that are actually switched on at the same time. Running load is used for backup and inverter planning.
How do tariff slabs work?
Tariff slabs apply different rates to different ranges of units. For example, the first 100 units may be charged at a lower rate, while units above 400 may be costlier. Slab billing increases the bill faster as consumption grows.
Where can I compare my electricity usage?
Use the appliance electricity cost calculator for individual appliance estimates, and the monthly electricity bill calculator India for your whole-bill estimate.
