About these units
BTU per Hour (BTU/h): BTU per hour is used to rate air conditioners and heaters. 12,000 BTU/h is one ton of refrigeration.
Tons of Refrigeration (TR): A ton of refrigeration (TR) is 12,000 BTU/h, about 3.517 kW. Air-conditioning systems in the Gulf and Asia are sized in tons.
Frequently asked questions
How many tons of refrigeration are in 1 BTU per hour?
1 BTU per hour (BTU/h) equals 0.000083333333 tons of refrigeration (TR).
How do I convert BTU/h to TR?
Multiply the value in BTU per hour by 0.000083333333. For example, 5 BTU/h × 0.000083333333 = 0.000416666667 TR.
How do I convert tons of refrigeration back to BTU per hour?
Multiply by 12,000 (or divide by 0.000083333333). 1 TR = 12,000 BTU/h.
What does BTU/h mean?
BTU per hour is used to rate air conditioners and heaters. 12,000 BTU/h is one ton of refrigeration.
