Power Conversion Formula:
From: | To: |
kW (kilowatt) is a unit of power that measures the rate of energy transfer, while kWh (kilowatt-hour) is a unit of energy that measures the total amount of electricity consumed over time. One kWh equals the energy used by a 1 kW device running for one hour.
The calculator uses the power conversion formula:
Where:
Explanation: This formula converts energy consumption (kWh) to power (kW) by dividing the total energy by the time period over which it was consumed.
Details: Understanding the relationship between energy and power is essential for energy management, electrical system design, and calculating the power requirements of devices and systems.
Tips: Enter the total energy consumption in kWh and the time period in hours. Both values must be positive numbers greater than zero.
Q1: What's the difference between kW and kWh?
A: kW measures power (rate of energy use), while kWh measures energy (total consumption over time).
Q2: Can I use this for solar panel calculations?
A: Yes, this calculator can help determine the power output needed from solar panels based on your energy consumption over time.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact when you have consistent power consumption over the measured time period.
Q4: What if my power consumption isn't constant?
A: This calculation gives you the average power over the time period. For variable consumption, you may need more detailed analysis.
Q5: Can I convert kW back to kWh?
A: Yes, to convert back, multiply kW by hours: kWh = kW × hours.
