Watts to kWh Formula:
From: | To: |
The Watts to kWh conversion calculates energy consumption by converting power (watts) over time (hours) into kilowatt-hours, the standard unit of energy used by electric utilities.
The calculator uses the simple formula:
Where:
Explanation: This converts watt-hours to kilowatt-hours by dividing by 1000, since 1 kilowatt equals 1000 watts.
Details: Calculating energy consumption helps estimate electricity costs, compare appliance efficiency, and understand power usage patterns.
Tips: Enter power consumption in watts and usage time in hours. Both values must be positive numbers.
Q1: How many kWh is 1000 watts for 1 hour?
A: Exactly 1 kWh (1000 watts × 1 hour ÷ 1000 = 1 kWh)
Q2: What's the difference between watts and kilowatt-hours?
A: Watts measure power (rate of energy use), while kWh measure energy (power × time).
Q3: How can I estimate my electricity bill with this?
A: Multiply kWh result by your electricity rate (per kWh) to estimate cost.
Q4: Why divide by 1000?
A: To convert from watt-hours (Wh) to kilowatt-hours (kWh), since 1 kW = 1000 W.
Q5: Can I use this for solar panel calculations?
A: Yes, this works for any electrical power source when calculating energy production/consumption.
