1. What is kWh?

kWh (kilowatt-hour) is a unit of energy that represents the amount of electricity consumed over time. It's commonly used for billing electrical energy by utility companies.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{kW} \) — Power in kilowatts
• \( \text{Hours} \) — Time in hours

Explanation: The formula calculates energy consumption by multiplying power (in kW) by time (in hours).

3. Importance of kWh Calculation

Details: Calculating kWh helps estimate electricity costs, understand energy consumption patterns, and compare efficiency of electrical devices.

4. Using the Calculator

Tips: Enter power in kilowatts (kW) and time in hours. Both values must be positive numbers. For devices rated in watts, divide by 1000 to convert to kW.

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 (power × time).

Q2: How do I convert watts to kW?
A: Divide watts by 1000 (1 kW = 1000 watts).

Q3: Can I use this for solar panel calculations?
A: Yes, it works for any electrical power source when you know the kW rating and operating hours.

Q4: How accurate is this calculation?
A: It's accurate for constant power consumption. For variable loads, more complex calculations are needed.

Q5: How does this relate to my electricity bill?
A: Utility companies charge per kWh consumed. Multiply kWh by your rate to estimate costs.
