FAQ

What is the conversion factor from TR to hp?
1 TR equals 4.716177 hp. To convert, multiply the value in tons of refrigeration by 4.716177.
How do I convert 1 TR to hp?
1 TR = 4.71618 hp. For any value, multiply by 4.716177.
How do I convert hp back to TR?
Divide by the same factor — or equivalently, multiply by 0.2120361. So 1 hp = 0.212036 TR.
When would I need to convert ton of refrigeration to mechanical 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).
