1. What is kWh?

A kilowatt-hour (kWh) is a unit of energy that represents the amount of electricity consumed by a 1,000-watt appliance running for one hour. It's the standard unit used by utility companies for billing purposes.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( P \) — Power in watts (W)
• \( m \) — Time in minutes
• 60 — Converts minutes to hours
• 1000 — Converts watts to kilowatts

Explanation: The formula converts minutes to hours (dividing by 60) and watts to kilowatts (dividing by 1000) to calculate the energy consumption in kWh.

3. Importance of Energy Calculation

Details: Calculating energy consumption helps in understanding electricity usage, estimating costs, and making energy-efficient choices for appliances and devices.

4. Using the Calculator

Tips: Enter the power consumption of your device in watts and the duration of use in minutes. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How many kWh is 1000 watts for 1 hour?
A: 1000 watts for 1 hour equals exactly 1 kWh (1000 × 1 / 1000 = 1 kWh).

Q2: How do I convert kWh to cost?
A: Multiply kWh by your electricity rate (price per kWh) to get the cost.

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

Q4: Can I use this for solar panel calculations?
A: Yes, you can calculate energy production by entering panel wattage and sunlight duration.

Q5: How accurate is this calculation?
A: It's mathematically precise, but actual consumption may vary based on device efficiency and power fluctuations.
