1. What is an Electricity Unit Consumption Calculator?

Definition: This calculator estimates electricity consumption in kilowatt-hours (kWh) based on appliance power rating and usage time.

Purpose: It helps Indian households and businesses estimate their electricity bills and manage power consumption.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Electricity units (kWh)
• \( P \) — Power consumption (watts)
• \( t \) — Usage time (hours)

Explanation: The formula converts watt-hours to kilowatt-hours (units) by dividing by 1000, which is the standard billing unit in India.

3. Importance of Electricity Unit Calculation

Details: Accurate unit calculation helps in budgeting electricity expenses, comparing appliance efficiency, and reducing energy waste.

4. Using the Calculator

Tips: Enter the appliance's power rating in watts and daily usage time in hours. For monthly calculation, multiply daily usage by 30.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my appliance's power rating?
A: Check the nameplate or manual. Typical ratings: LED bulb (9-15W), fan (50-75W), AC (1500-3000W).

Q2: What's the electricity rate per unit in India?
A: Varies by state and consumption slab, typically ₹3-₹8 per unit for households.

Q3: How can I reduce my electricity units?
A: Use energy-efficient appliances, reduce usage time, and maintain equipment properly.

Q4: Does this include all charges on my bill?
A: No, this calculates only consumption. Bills include fixed charges, taxes, and other fees.

Q5: How accurate is this calculation?
A: It provides theoretical consumption. Actual may vary based on voltage fluctuations and appliance condition.
