How to Convert Ton of Refrigeration to Kilowatt
- 1 TR = 3.516852842 kW
- 1 kW = 0.2843451361 TR
- Example: convert 15 TR to kW: 15 TR = 15 × 3.516852842 kW = 52.75279263 kW
Formula
kW = TR × 3.516852842067
Derivation from SI units:
- 1 TR = 12 000 BTU/h = 3516.8528420667 W
- 1 kW = 10³ W
- 1 TR = 3516.852842067 W ÷ 1000 W per kW = 3.516852842067 kW
Both units are defined exactly, so the factor is exact. Ton of Refrigeration definition: ton of refrigeration; Kilowatt definition: kilowatt.
Worked examples
- A 3 TR split system cools 10.55055853 kW.
3 TR × 3.516852842 = 10.55055853 kW - A 500 TR chiller is 1758.426421 kW.
500 TR × 3.516852842 = 1758.426421 kW
