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 provided by utility companies.

2. How Does the Calculator Work?

The calculator uses the basic energy formula:

Where:

• \( kWh \) — Kilowatt-hours (energy)
• \( Power \) — Power in kilowatts (kW)
• \( Time \) — Time in hours (h)

Explanation: The formula calculates energy consumption by multiplying power usage by the duration of use.

3. Importance of kWh Calculation

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

4. Using the Calculator

Tips: Enter power in kilowatts (kW) and time in hours. For appliances rated in watts, divide by 1000 to convert to kW (1 kW = 1000W).

5. Frequently Asked Questions (FAQ)

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

Q2: How do I calculate kWh for minutes instead of hours?
A: Convert minutes to hours by dividing by 60 (e.g., 30 minutes = 0.5 hours).

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

Q4: How can I estimate my electricity bill using kWh?
A: Multiply total kWh by your electricity rate (price per kWh).

Q5: What's a typical kWh consumption for household appliances?
A: Varies by appliance - a 100W bulb running for 10 hours uses 1 kWh (0.1kW × 10h).
