Energy Conversion Formula:
From: | To: |
The Watt to kilowatt-hour (kWh) conversion calculates energy consumption by converting power (watts) over time (hours) into energy units (kWh). This is essential for understanding electricity usage and costs.
The calculator uses the energy conversion formula:
Where:
Explanation: Since 1 kilowatt equals 1000 watts, we divide by 1000 to convert watt-hours to kilowatt-hours.
Details: Understanding energy consumption in kWh helps estimate electricity costs, compare appliance efficiency, and calculate carbon footprint.
Tips: Enter power in watts and duration in hours. Both values must be positive numbers. The result shows energy consumption in kilowatt-hours.
Q1: Why convert watts to kWh?
A: Utility companies bill in kWh, so converting helps estimate electricity costs from appliance power ratings.
Q2: How much is 1 kWh?
A: 1 kWh equals 1000 watts running for 1 hour, or equivalent combinations (e.g., 100W for 10 hours).
Q3: What's the difference between watts and kWh?
A: Watts measure power (rate of energy use), while kWh measures energy (power × time).
Q4: How accurate is this calculation?
A: It assumes constant power draw. Actual consumption may vary with usage patterns and device efficiency.
Q5: Can I use this for solar panel calculations?
A: Yes, it helps estimate energy production (wattage × sunlight hours ÷ 1000 = kWh generated).
