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 using 1,000 watts of power for one hour. It's the standard unit used by utility companies for billing.

2. How Does the Calculator Work?

The calculator uses the simple energy formula:

Where:

• \( \text{kW} \) — Power in kilowatts (1 kW = 1000 watts)
• \( \text{hours} \) — Time duration in hours
• \( \text{kWh} \) — Energy consumption in kilowatt-hours

Explanation: This calculation shows how much energy is used when a certain power level is maintained for a specific time period.

3. Importance of Energy Calculation

Details: Calculating kWh helps estimate electricity costs, size solar power systems, compare appliance efficiency, and understand energy consumption patterns.

4. Using the Calculator

Tips: Enter power in kilowatts (for example: 1.5 kW for a 1500W appliance) and time in hours (can use decimals for minutes, e.g., 0.5 = 30 minutes).

5. Frequently Asked Questions (FAQ)

Q1: How do I convert watts to kilowatts?
A: Divide watts by 1000 (e.g., 1500W = 1.5 kW).

Q2: How do I convert minutes to hours?
A: Divide minutes by 60 (e.g., 45 minutes = 0.75 hours).

Q3: What's the difference between kW and kWh?
A: kW measures power (rate of energy use), kWh measures energy (total consumption over time).

Q4: How much does 1 kWh cost?
A: Costs vary by location and provider, typically $0.10-$0.30 per kWh in the US.

Q5: Can I use this for solar panel calculations?
A: Yes, this helps estimate how much energy your solar system needs to produce to cover your consumption.
