⚡ What is an Electricity Calculator?

An Electricity Calculator helps you estimate your power consumption and electricity bill based on appliance usage.

👉 It shows:

• Units consumed (kWh)
• Total electricity cost
• Monthly/annual bill

🎯 How to Use an Electricity Calculator

1. Enter Power Rating (Watts)
   • Example: 1000W (1 kW)
2. Enter Usage Time (Hours per day)
   • Example: 5 hours
3. Enter Number of Days
   • Example: 30 days
4. Enter Cost per Unit (₹/kWh)
   • Example: ₹8
5. Click “Calculate”
6. View Result
   • Total units consumed
   • Total electricity bill

📊 Formula Used

👉 Units (kWh) = (Watt × Hours × Days) / 1000
👉 Cost = Units × Price per unit

📊 Example

👉 Power = 1000W
👉 Usage = 5 hours/day
👉 Days = 30
👉 Rate = ₹8/unit

➡️ Units = (1000 × 5 × 30) / 1000 = 150 kWh
➡️ Cost = 150 × 8 = ₹1200
