FAQ
What is the conversion factor from TR to cal/s?
1 TR equals 840.548 cal/s. To convert, multiply the value in tons of refrigeration by 840.548.
How do I convert 1 TR to cal/s?
1 TR = 840.548 cal/s. For any value, multiply by 840.548.
How do I convert cal/s back to TR?
Divide by the same factor — or equivalently, multiply by 0.0011897. So 1 cal/s = 0.0011897 TR.
When would I need to convert ton of refrigeration 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).
