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

0.5 RT6,000 BTU/hr
1 RT12,000 BTU/hr
1.5 RT18,000 BTU/hr
2 RT24,000 BTU/hr
2.5 RT30,000 BTU/hr
3 RT36,000 BTU/hr
4 RT48,000 BTU/hr
5 RT60,000 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.
