Factor1 TR = 3.333333 BTU/s

Converter

TR

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

Result
3.33333BTU/s

Rendered to 6 significant figures.

Formula

Formula
BTU/s = TR × 3.333333

Multiply any value in tons of refrigeration by 3.333333 to obtain the value in British thermal units per second.

Worked example

Convert 1 TR to BTU/s.

  1. 01Start with 1 TR.
  2. 02Multiply by the conversion factor: 1 × 3.333333 = 3.33333 BTU/s.
Result1 TR = 3.33333 BTU/s

FAQ

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