1. What is kWh?

A kilowatt-hour (kWh) is a unit of energy that represents the amount of electricity consumed over time. One kWh equals the energy used by a 1,000-watt appliance running for one hour.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{Power} \) — The rate of energy consumption in kilowatts (kW)
• \( \text{Time} \) — Duration of usage in hours
• \( \text{Energy} \) — Total energy consumed in kilowatt-hours (kWh)

Explanation: This calculation helps determine electricity usage for billing, energy monitoring, and efficiency assessments.

3. Importance of Energy Calculation

Details: Understanding energy consumption helps in budgeting electricity costs, comparing appliance efficiency, and reducing energy waste.

4. Using the Calculator

Tips: Enter power in kilowatts (kW) and time in hours. For appliances rated in watts, divide by 1,000 to convert to kW (e.g., 1,500W = 1.5kW).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between kW and kWh?
A: kW measures power (rate of energy use), while kWh measures energy (total consumption over time).

Q2: How do I convert watts to kW?
A: Divide watts by 1,000 (e.g., 2,000W = 2kW).

Q3: How can I estimate my electricity bill?
A: Multiply kWh by your electricity rate (price per kWh).

Q4: What's a typical kWh usage for a home?
A: Average U.S. household uses about 900 kWh per month, but varies by location and appliances.

Q5: Can I use this for solar panel calculations?
A: Yes, it works the same way - multiply panel output (kW) by hours of sunlight to estimate production.
