1. What is the Watts to kWh Conversion?

The Watts to kWh conversion calculates energy consumption by converting power (watts) over time (hours) into kilowatt-hours, the standard unit for electrical energy billing.

2. How Does the Calculator Work?

The calculator uses the energy formula:

Where:

• \( kWh \) — Kilowatt-hours (energy unit)
• \( W \) — Power in watts
• \( h \) — Time duration in hours
• 1000 — Conversion factor (watts to kilowatts)

Explanation: This formula converts power consumption over time into the standard energy unit used by utility companies.

3. Importance of Energy Calculation

Details: Calculating energy consumption helps estimate electricity costs, compare appliance efficiency, and understand power usage patterns.

4. Using the Calculator

Tips: Enter power consumption in watts and time duration in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between watts and watt-hours?
A: Watts measure power (rate of energy use), while watt-hours measure energy (power × time).

Q2: How do I convert kWh to electricity cost?
A: Multiply kWh by your electricity rate (per kWh) from your utility bill.

Q3: What's a typical wattage for household appliances?
A: LED bulb: 10W, Laptop: 50W, Refrigerator: 100-400W, Microwave: 700-1200W.

Q4: Why divide by 1000?
A: To convert watts to kilowatts (1 kW = 1000 W), since energy is typically billed in kWh.

Q5: Can I use this for solar panel calculations?
A: Yes, to estimate energy production by multiplying panel wattage by sunlight hours.
