FAQ
What is the conversion factor from kW to W?
1 kW equals 1000 W. To convert, multiply the value in kilowatts by 1000.
How do I convert 1 kW to W?
1 kW = 1000 W. For any value, multiply by 1000.
How do I convert W back to kW?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 W = 0.001 kW.
When would I need to convert kilowatt to watt?
Power conversions are common when comparing motor ratings (often kW or hp), thermal duty (BTU/hr or kW), and utility consumption in mixed-unit projects.
Is the conversion exact?
Yes. Both kW and W are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
