How to convert BTU per hour to tons of refrigeration
TR = BTU/h × 0.00008333333333Because one ton of refrigeration equals 12,000 BTU per hour, you can also divide: TR = BTU/h ÷ 12,000.
A BTU per hour is smaller than a ton of refrigeration: it takes 12,000 BTU per hour to make one ton of refrigeration.

About the units
BTU per hour (BTU/h)
About 0.293 W. Air conditioners and furnaces are rated in BTU/h — a 12,000 BTU/h unit is one ton of cooling. One BTU per hour equals 0.2930710702 watts (W).
Ton of refrigeration (TR)
12,000 BTU/h (about 3.517 kW), historically the cooling from melting one short ton of ice per day. One ton of refrigeration equals 3,516.852842 watts (W).
Frequently asked questions
How many tons of refrigeration are in one BTU per hour?
There are 0.00008333333333 tons of refrigeration in one BTU per hour, and this value is exact by definition.
How do I convert BTU per hour to tons of refrigeration?
Multiply the number of BTU per hour by 0.00008333333333. For example, 10 BTU/h × 0.00008333333333 = 0.0008333333333 TR.
