FAQ

What is the conversion factor from kW to hp?
1 kW equals 1.341022 hp. To convert, multiply the value in kilowatts by 1.341022.
How do I convert 1 kW to hp?
1 kW = 1.34102 hp. For any value, multiply by 1.341022.
How do I convert hp back to kW?
Divide by the same factor — or equivalently, multiply by 0.7456999. So 1 hp = 0.7457 kW.
When would I need to convert kilowatt to mechanical horsepower?
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?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
