FAQ

What is the conversion factor from hp to BTU/s?
1 hp equals 0.7067871 BTU/s. To convert, multiply the value in mechanical horsepower by 0.7067871.
How do I convert 1 hp to BTU/s?
1 hp = 0.706787 BTU/s. For any value, multiply by 0.7067871.
How do I convert BTU/s back to hp?
Divide by the same factor — or equivalently, multiply by 1.414853. So 1 BTU/s = 1.41485 hp.
When would I need to convert mechanical horsepower to British thermal unit per second?
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).
