FAQ

What is the conversion factor from TR to PS?
1 TR equals 4.781589 PS. To convert, multiply the value in tons of refrigeration by 4.781589.
How do I convert 1 TR to PS?
1 TR = 4.78159 PS. For any value, multiply by 4.781589.
How do I convert PS back to TR?
Divide by the same factor — or equivalently, multiply by 0.2091355. So 1 PS = 0.209135 TR.
When would I need to convert ton of refrigeration to metric horsepower?
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).
