About this calculator

This ton to kW converter converts refrigeration tonnage to kilowatts of cooling power using the standard 3.517 kW per refrigeration ton.

Formula notes

Cooling power (kW) = refrigeration tonnage × 3.517.

Worked examples

  1. Example: 5 refrigeration tons equals 17.585 kW.
  2. 2 refrigeration tons equals 7.034 kW of cooling power.

How to use it

  1. Enter the refrigeration tonnage.
  2. Or enter kilowatts to convert back to tons.
  3. Read the converted cooling power.

Frequently asked questions

Is this the same ton as weight?

No. Refrigeration ton is a unit of cooling rate equal to 12,000 BTU/h, not a mass ton.

Can I convert BTU/h or watts too?

This converter focuses on ton-to-kW. For BTU/h or watts, use a dedicated power or cooling conversion tool.

Limits and interpretation

  • The 3.517 factor is the common refrigeration-ton-to-kW conversion; exact equipment efficiency may vary.
  • This is cooling rate conversion, not electrical power consumption of an air conditioner.
