From: | To: |
The conversion from watt-hours (Wh) to kilowatt-hours (kWh) is a basic unit conversion in energy measurement. It's commonly used in home energy monitoring to understand electricity usage in more familiar terms.
The calculator uses the simple conversion formula:
Where:
Explanation: Since "kilo" means 1000, 1 kilowatt-hour equals 1000 watt-hours. This conversion helps express energy usage in more manageable numbers for typical household consumption.
Details: Most utility companies bill in kWh, while many small devices report energy consumption in Wh. Converting between these units helps consumers understand their energy usage patterns and costs.
Tips: Enter the watt-hours value you want to convert. The value must be positive. The calculator will automatically compute the equivalent kilowatt-hours.
Q1: Why convert Wh to kWh?
A: kWh is the standard unit for electricity billing and better represents typical home energy usage, as most homes consume thousands of watt-hours daily.
Q2: How many Wh are in 1 kWh?
A: There are exactly 1000 watt-hours in 1 kilowatt-hour.
Q3: What's the difference between watts and watt-hours?
A: Watts measure power (rate of energy use), while watt-hours measure energy (power × time). A 100W device running for 10 hours uses 1000Wh (1kWh).
Q4: Is this conversion only for electricity?
A: While commonly used for electricity, the Wh and kWh units can technically measure any form of energy, though they're most often used for electrical energy.
Q5: How accurate is this conversion?
A: The conversion is mathematically exact - there's no rounding or approximation in the basic conversion factor of 1000.
