FAQ
What is the conversion factor from PS to cal/s?
1 PS equals 175.7884 cal/s. To convert, multiply the value in metric horsepower by 175.7884.
How do I convert 1 PS to cal/s?
1 PS = 175.788 cal/s. For any value, multiply by 175.7884.
How do I convert cal/s back to PS?
Divide by the same factor — or equivalently, multiply by 0.005688657. So 1 cal/s = 0.00568866 PS.
When would I need to convert metric horsepower to calorie 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).
