Formula
GW = PS × 7.354988e-7
Multiply any value in metric horsepower by 7.354988e-7 to obtain the value in gigawatts.
Worked example
Convert 1.00000e+6 PS to GW.
- 01Start with 1.00000e+6 PS.
- 02Multiply by the conversion factor: 1.00000e+6 × 7.354988e-7 = 0.735499 GW.
Result1.00000e+6 PS = 0.735499 GW

FAQ
What is the conversion factor from PS to GW?
1 PS equals 7.354988e-7 GW. To convert, multiply the value in metric horsepower by 7.354988e-7.
How do I convert 1 PS to GW?
1 PS = 7.35499e-7 GW. For any value, multiply by 7.354988e-7.
How do I convert GW back to PS?
Divide by the same factor — or equivalently, multiply by 1359622. So 1 GW = 1.35962e+6 PS.
When would I need to convert metric horsepower to gigawatt?
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).
