Watts to kWh Formula:
From: | To: |
The Watts to kWh calculation converts power consumption (watts) into energy usage (kilowatt-hours). This is essential for understanding electricity consumption and calculating energy costs.
The calculator uses the simple formula:
Where:
Explanation: The formula accounts for both the power rating of the device and the duration of use to calculate total energy consumption.
Details: Understanding energy consumption helps in estimating electricity costs, comparing appliance efficiency, and managing energy usage for sustainability.
Tips: Enter the device's power rating in watts and the duration of use in hours. Both values must be positive numbers.
Q1: What's the difference between watts and kilowatt-hours?
A: Watts measure power (rate of energy use), while kilowatt-hours measure energy (total consumption over time).
Q2: How can I find my appliance's wattage?
A: Check the label or manual. If only amps and volts are listed, multiply them (W = A × V).
Q3: Why divide by 1000?
A: To convert from watts (W) to kilowatts (kW), as energy is typically billed in kWh.
Q4: Can I use this for solar panel calculations?
A: Yes, it works for both energy consumption and production calculations.
Q5: How accurate is this calculation?
A: It's accurate for constant loads. For variable loads, you may need more complex measurements.
