Refrigeration Tons to BTU/hr Converter
Convert HVAC cooling capacity from refrigeration tons to BTU/hr. Multiply tons by 12,000 to get BTU/hr.
⚡
Refrigeration Ton ↔ BTU per hour
Calculation Formula
1 RT × 12,000 = 12,000 BTU/hr
Worked Example
Convert 3 Tons to BTU/hr:
3 Tons × 12,000 = 36,000 BTU/hr
Refrigeration Ton to BTU per hour Table
| RT | BTU/hr |
|---|---|
| 0.5 RT | 6,000 BTU/hr |
| 1 RT | 12,000 BTU/hr |
| 1.5 RT | 18,000 BTU/hr |
| 2 RT | 24,000 BTU/hr |
| 2.5 RT | 30,000 BTU/hr |
| 3 RT | 36,000 BTU/hr |
| 4 RT | 48,000 BTU/hr |
| 5 RT | 60,000 BTU/hr |
Understanding the Conversion
While central air conditioners are often sold by the ton (e.g., a 3-ton unit), ductless mini-splits and window units are usually rated directly in BTU/hr.
Compare heating & cooling costs.
Use your converted HVAC ratings to compare the running costs of heat pumps versus gas furnaces.
