Formula
Formula
TR = J/s × 0.0002843451
Multiply any value in joules per second by 0.0002843451 to obtain the value in tons of refrigeration.
Worked example
Convert 100000 J/s to TR.
- 01Start with 100000 J/s.
- 02Multiply by the conversion factor: 100000 × 0.0002843451 = 28.4345 TR.
Result100000 J/s = 28.4345 TR

FAQ
What is the conversion factor from J/s to TR?
1 J/s equals 0.0002843451 TR. To convert, multiply the value in joules per second by 0.0002843451.
How do I convert 1 J/s to TR?
1 J/s = 0.000284345 TR. For any value, multiply by 0.0002843451.
How do I convert TR back to J/s?
Divide by the same factor — or equivalently, multiply by 3516.853. So 1 TR = 3516.85 J/s.
When would I need to convert joule 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).
