Formula
Formula
TR = BTU/s × 0.3
Multiply any value in British thermal units per second by 0.3 to obtain the value in tons of refrigeration.
Worked example
Convert 100 BTU/s to TR.
- 01Start with 100 BTU/s.
- 02Multiply by the conversion factor: 100 × 0.3 = 30 TR.
Result100 BTU/s = 30 TR

FAQ
What is the conversion factor from BTU/s to TR?
1 BTU/s equals 0.3 TR. To convert, multiply the value in British thermal units per second by 0.3.
How do I convert 1 BTU/s to TR?
1 BTU/s = 0.3 TR. For any value, multiply by 0.3.
How do I convert TR back to BTU/s?
Divide by the same factor — or equivalently, multiply by 3.333333. So 1 TR = 3.33333 BTU/s.
When would I need to convert British thermal unit 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).
