1. What is Kilowatt Hours?

A kilowatt-hour (kWh) is a unit of energy that represents the amount of electricity consumed over time. It's commonly used by utility companies to measure and bill for energy usage.

2. How Does the Calculator Work?

The calculator uses the simple equation:

Where:

• \( Power \) — Power consumption in kilowatts (kW)
• \( Time \) — Time duration in hours (h)

Explanation: The equation multiplies power consumption by time to calculate total energy usage.

3. Importance of kWh Calculation

Details: Calculating kWh helps understand energy consumption patterns, estimate electricity costs, and make informed decisions about energy efficiency.

4. Using the Calculator

Tips: Enter power in kilowatts (1 kW = 1000 watts) and time in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert watts to kilowatts?
A: Divide watts by 1000 (1 kW = 1000W). For example, 1500W = 1.5kW.

Q2: How is kWh different from kW?
A: kW measures power (rate of energy use), while kWh measures energy (power × time).

Q3: How many kWh does a typical home use?
A: Average U.S. household uses about 877 kWh per month (29 kWh/day).

Q4: Can I calculate cost from kWh?
A: Yes, multiply kWh by your electricity rate (e.g., 10 kWh × $0.12/kWh = $1.20).

Q5: What's the difference between kWh and kW per hour?
A: "kW per hour" is incorrect terminology. The correct unit is kWh (kilowatt-hours).
