FAQ

What is the conversion factor from hp to BTU/min?
1 hp equals 42.40723 BTU/min. To convert, multiply the value in mechanical horsepower by 42.40723.
How do I convert 1 hp to BTU/min?
1 hp = 42.4072 BTU/min. For any value, multiply by 42.40723.
How do I convert BTU/min back to hp?
Divide by the same factor — or equivalently, multiply by 0.02358089. So 1 BTU/min = 0.0235809 hp.
When would I need to convert mechanical horsepower to British thermal unit per minute?
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).
