Refrigeration Tons to BTU per Hour

One refrigeration ton is equal to 12000 BTUs per hour, so moving from RT to BTU/hr takes a single multiplication. Type the tonnage, press Convert, and the matching figure in BTU/hr appears below.

Refrigeration tons and BTU per hour

The refrigeration ton (RT) and the BTU per hour (BTU/hr) are both units of power, which means a value written in one of them can be restated in the other with no extra information. The link between the two is fixed: 1 RT = 12000 BTU/hr.

Going the other direction works just as directly, because 1 BTU/hr ≈ 0.0000833333 RT. That reciprocal is tiny, so any non-zero tonnage has a much larger magnitude when the same power is expressed in BTU/hr instead of refrigeration tons.

RT to BTU/hr formula

The power P in BTUs per hour is 12000 times the power P in refrigeration tons:

P (BTU/hr) = 12000 × P (RT)

For example, converting 2 RT gives P (BTU/hr) = 12000 × 2 RT = 24000 BTU/hr. Any other tonnage follows the same path — multiply it by 12000 and the answer is already in BTU/hr.
