How to Convert Ton of Refrigeration to Watt
- 1 TR = 3516.852842 W
- 1 W = 0.0002843451361 TR
- Example: convert 15 TR to W: 15 TR = 15 × 3516.852842 W = 52752.79263 W
Formula
W = TR × 3516.852842067
Derivation from SI units:
- 1 TR = 12 000 BTU/h = 3516.8528420667 W
- 1 W = 1 J/s = 1 kg·m²·s⁻³
Both units are defined exactly, so the factor is exact. Ton of Refrigeration definition: ton of refrigeration; Watt definition: watt.
Worked examples
- A reading of 2.5 TR converts to 8792.132105 W.
2.5 TR × 3516.852842 = 8792.132105 W - A value of 10 TR is 35168.52842 W.
10 TR × 3516.852842 = 35168.52842 W
