Conversion Reference:
  • 1 Refrigeration Ton (RT) = 12,000 BTU/hr
  • 1 RT = 3.517 kW (cooling capacity)
  • 1 kW = 3,412.14 BTU/hr
  • 1 MBTU = 1,000 BTU
Typical Cooling Capacities
Window AC
0.5 - 2 tons
6,000 - 24,000 BTU/hr
Split System
1 - 5 tons
12,000 - 60,000 BTU/hr
Rooftop
3 - 20 tons
36,000 - 240,000 BTU/hr
Chiller
15 - 1000+ tons
180,000 - 12,000,000+ BTU/hr
These ranges represent common capacities for each type of system.

Note: All calculations are based on standard HVAC industry conversion factors.

One refrigeration ton is equal to 12000 BTUs per hour:

1 RT = 12000 BTU/hr

One BTU per hour is equal to 8.33333×10-5 refrigeration ton:

1 BTU/hr = 8.33333×10-5 RT

 

So the power P in BTUs per hour (BTU/hr) is equal to 12000 times the power P in refrigeration tons (RT):

P(BTU/hr) = 12000 × P(RT)

 

Example

Convert 2 RT to BTU/hr:

P(BTU/hr) = 12000 × 2 RT = 24000 BTU/hr
