FAQ

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