Formula
Formula
TR = BTU/min × 0.005
Multiply any value in British thermal units per minute by 0.005 to obtain the value in tons of refrigeration.
Worked example
Convert 1000 BTU/min to TR.
- 01Start with 1000 BTU/min.
- 02Multiply by the conversion factor: 1000 × 0.005 = 5 TR.
Result1000 BTU/min = 5 TR

FAQ
What is the conversion factor from BTU/min to TR?
1 BTU/min equals 0.005 TR. To convert, multiply the value in British thermal units per minute by 0.005.
How do I convert 1 BTU/min to TR?
1 BTU/min = 0.005 TR. For any value, multiply by 0.005.
How do I convert TR back to BTU/min?
Divide by the same factor — or equivalently, multiply by 200. So 1 TR = 200 BTU/min.
When would I need to convert British thermal unit per minute 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).
