FAQ
What is the conversion factor from GW to hp?
1 GW equals 1341022 hp. To convert, multiply the value in gigawatts by 1341022.
How do I convert 1 GW to hp?
1 GW = 1.34102e+6 hp. For any value, multiply by 1341022.
How do I convert hp back to GW?
Divide by the same factor — or equivalently, multiply by 7.456999e-7. So 1 hp = 7.457e-7 GW.
When would I need to convert gigawatt 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).
