FAQ

What is the conversion factor from BTU/hr to PS?
1 BTU/hr equals 0.0003984658 PS. To convert, multiply the value in British thermal units per hour by 0.0003984658.
How do I convert 1 BTU/hr to PS?
1 BTU/hr = 0.000398466 PS. For any value, multiply by 0.0003984658.
How do I convert PS back to BTU/hr?
Divide by the same factor — or equivalently, multiply by 2509.626. So 1 PS = 2509.63 BTU/hr.
When would I need to convert British thermal unit per hour 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).
