FAQ
What is the conversion factor from cal/s to hp?
1 cal/s equals 0.005610836 hp. To convert, multiply the value in calories per second by 0.005610836.
How do I convert 1 cal/s to hp?
1 cal/s = 0.00561084 hp. For any value, multiply by 0.005610836.
How do I convert hp back to cal/s?
Divide by the same factor — or equivalently, multiply by 178.2265. So 1 hp = 178.227 cal/s.
When would I need to convert calorie per second to mechanical 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).
