FAQ
What is the conversion factor from kcal/hr to hp?
1 kcal/hr equals 0.001559609 hp. To convert, multiply the value in kilocalories per hour by 0.001559609.
How do I convert 1 kcal/hr to hp?
1 kcal/hr = 0.00155961 hp. For any value, multiply by 0.001559609.
How do I convert hp back to kcal/hr?
Divide by the same factor — or equivalently, multiply by 641.1865. So 1 hp = 641.186 kcal/hr.
When would I need to convert kilocalorie per hour 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).
