FAQ

What is the conversion factor from BTU/s to PS?
1 BTU/s equals 1.434477 PS. To convert, multiply the value in British thermal units per second by 1.434477.
How do I convert 1 BTU/s to PS?
1 BTU/s = 1.43448 PS. For any value, multiply by 1.434477.
How do I convert PS back to BTU/s?
Divide by the same factor — or equivalently, multiply by 0.6971183. So 1 PS = 0.697118 BTU/s.
When would I need to convert British thermal unit per second to metric 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).
