Energy FAQs

1. How to calculate electricity cost from Watts?
Multiply the wattage of the appliance by the number of hours used per day, then divide by 1,000 to get the daily KWh. Multiply this by your local electricity rate per unit.
2. What is 1 unit of electricity?
In India, 1 unit of electricity is equal to 1 Kilowatt-hour (KWh), which is the energy consumed by a 1,000-watt appliance running for one hour.
3. How much does an AC cost per hour in India 2026?
A typical 1.5-ton 5-star AC uses roughly 1-1.5 units per hour. At a rate of ₹8/unit, it costs approximately ₹8-12 per hour of operation.
4. Why is my electricity bill so high?
High bills often stem from inefficient appliances, phantom power (devices on standby), or high-consumption units like geysers and air conditioners.
5. How many watts does a ceiling fan use?
A standard ceiling fan uses about 50-75 watts, while modern BLDC fans consume only 28-35 watts, significantly reducing costs.
6. Does the calculator account for fixed charges?
No, this tool calculates the energy charge based on usage. Your final bill may include fixed meter charges and government taxes/cess.
7. What is a KWh?
KWh stands for Kilowatt-hour, the standard unit used by electricity boards globally to measure and bill energy consumption.
8. Is it cheaper to use appliances at night?
In some Indian states with Time of Day (ToD) metering, electricity rates are lower during off-peak night hours.
9. How many units does a refrigerator consume?
A modern 250-liter frost-free refrigerator typically consumes 1-2 units per day depending on its star rating.
10. How to reduce my electricity bill?
Switch to LED lighting, use BLDC fans, maintain AC filters, and use the HQCalc tool to identify high-consumption devices.
