## Formula

- `1 kW = 0.284345 TR`
- `tons of refrigeration = kilowatts × 0.2843451361`
- Reverse: `kilowatts = tons of refrigeration × 3.516852842`

The factor follows from the SI definitions of both units (NIST SP 811); values below are rounded to 6 significant figures, the API returns up to 12.

## Worked examples

- 5 kW = 1.42173 TR
- 12.5 kW = 3.55431 TR
- 100 kW = 28.4345 TR
