TRtoBTU/hr

Convert tons of refrigeration (TR) to British thermal units per hour (BTU/hr).

Factor1 TR = 12000 BTU/hr

Converter

TR

Accepts numbers or expressions, e.g. 150 + 14.7

Result
12000BTU/hr

Rendered to 6 significant figures.

Formula

Formula
BTU/hr = TR × 12000

Multiply any value in tons of refrigeration by 12000 to obtain the value in British thermal units per hour.

Worked example

Convert 1 TR to BTU/hr.

  1. 01Start with 1 TR.
  2. 02Multiply by the conversion factor: 1 × 12000 = 12000 BTU/hr.
Result1 TR = 12000 BTU/hr

FAQ

What is the conversion factor from TR to BTU/hr?
1 TR equals 12000 BTU/hr. To convert, multiply the value in tons of refrigeration by 12000.
How do I convert 1 TR to BTU/hr?
1 TR = 12000 BTU/hr. For any value, multiply by 12000.
How do I convert BTU/hr back to TR?
Divide by the same factor — or equivalently, multiply by 8.333333e-5. So 1 BTU/hr = 8.33333e-5 TR.
When would I need to convert ton of refrigeration to British thermal unit per hour?
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).
