kW to kWh Calculator
Easily convert kilowatts (kW) to kilowatt-hours (kWh) using our calculator. Quick, accurate energy conversion for homes, industries, and solar usage.
Quick Intro: Convert kW to Kwh
The kW to kWh calculator helps convert electric power (kW) into energy (kWh) over time. Simply multiply the power in kilowatts by the duration in hours to find total energy consumed. This tool is widely used in solar system design, energy audits, and bill estimation.
Formula to Convert kW to Kwh
kWh = kW × Time (hours)
Where:
- kW = Power (kilowatts)
- Time = Duration (in hours)
- kWh = Energy used
kW to Kwh Calculator Overview
Convert kilowatts (kW) to kilowatt-hours (kWh) using this simple and accurate calculator. Just enter the power in kW and the time in hours to find the total energy consumed. Perfect for analyzing electricity usage in homes, factories, solar systems, and generators.

| Power (kW) | Time (Hours) | Energy (kWh) |
|---|---|---|
| 1 | 1 | 1 |
| 2 | 3 | 6 |
| 5 | 2 | 10 |
| 3 | 8 | 24 |
Frequently Asked Questions - kW to kWh Calculator:
How do I convert kW to kWh?
Multiply the power in kilowatts by the time in hours. Formula: kWh = kW × hours.
What is the difference between kW and kWh?
kW is power (instant rate); kWh is energy (total used over time).
How many kWh is 5 kW for 3 hours?
5 × 3 = 15 kWh.
Can I use this for solar panel output?
Yes. Enter your panel’s power in kW and the hours of sun exposure.
Does this work for generators?
Yes. You can estimate fuel usage by calculating energy output.
What if the power changes over time?
Break the period into intervals and sum each kW × hour segment.
Is 1 kW always equal to 1 kWh?
Only if the device runs for 1 hour.
How do electric companies charge?
They charge based on kWh consumed.
What’s the cost of 10 kWh if rate is $0.15/kWh?
10 × 0.15 = $1.50.
Can I convert back from kWh to kW?
Yes. Divide kWh by time: kW = kWh ÷ hours.
