Formula

Formula
TR = cal/s × 0.0011897

Multiply any value in calories per second by 0.0011897 to obtain the value in tons of refrigeration.

Worked example

Convert 10000 cal/s to TR.

  1. 01Start with 10000 cal/s.
  2. 02Multiply by the conversion factor: 10000 × 0.0011897 = 11.897 TR.
Result10000 cal/s = 11.897 TR

FAQ

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