1. What is Kilowatt-hour (kWh)?

A kilowatt-hour (kWh) is a unit of energy representing the amount of energy consumed or produced by a one-kilowatt power source operating for one hour. It's the standard unit for electricity billing.

2. How Does the Calculator Work?

The calculator uses the simple energy formula:

Where:

• \( \text{Power} \) — Rate of energy transfer in kilowatts (kW)
• \( \text{Time} \) — Duration in hours (h)
• \( \text{Energy} \) — Total energy in kilowatt-hours (kWh)

Explanation: This formula calculates the total energy consumption by multiplying power by time.

3. Importance of Energy Calculation

Details: Calculating energy consumption helps in understanding electricity usage, estimating costs, and planning energy efficiency measures.

4. Using the Calculator

Tips: Enter power in kilowatts (kW) and time in hours (h). Both values must be positive numbers.

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 kilowatts?
A: Divide watts by 1000 (1 kW = 1000 W). For example, 1500 W = 1.5 kW.

Q3: How can I estimate my electricity cost?
A: Multiply kWh by your electricity rate (e.g., 10 kWh × $0.15/kWh = $1.50).

Q4: What's a typical household energy consumption?
A: Varies widely, but average U.S. household uses about 900 kWh per month.

Q5: Can I use this for solar panel calculations?
A: Yes, it works for both consumption and production calculations.
