Conversion Formula:
From: | To: |
The conversion from kilowatt-hours (kWh) to watts (W) helps determine the average power consumption over a specific time period. While kWh measures energy (power over time), watts measure instantaneous power.
The calculator uses the conversion formula:
Where:
Explanation: Since 1 kilowatt equals 1000 watts, we multiply kWh by 1000 to convert to watt-hours, then divide by hours to get watts.
Details: This conversion is useful for understanding appliance power consumption, sizing solar power systems, and analyzing electricity bills.
Tips: Enter energy consumption in kWh and the time period in hours. Both values must be positive numbers.
Q1: What's the difference between watts and kilowatt-hours?
A: Watts measure power (energy per unit time), while kilowatt-hours measure energy (power × time).
Q2: Why multiply by 1000 in the formula?
A: Because 1 kilowatt = 1000 watts, so we convert kWh to Wh first.
Q3: Can I use this for solar panel calculations?
A: Yes, it helps determine the average power output needed from solar panels based on your energy needs.
Q4: How accurate is this calculation?
A: It gives average power over the time period. For variable power devices, actual instantaneous power may differ.
Q5: What if my time period is in minutes?
A: Convert minutes to hours first (divide by 60) before using the calculator.
