How to Convert Ton of Refrigeration to Milliwatt
- 1 TR = 3516852.842 mW
- 1 mW = 2.843451361 × 10⁻⁷ TR
- Example: convert 15 TR to mW: 15 TR = 15 × 3516852.842 mW = 52752792.63 mW
Formula
mW = TR × 3516852.842067
Derivation from SI units:
- 1 TR = 12 000 BTU/h = 3516.8528420667 W
- 1 mW = 10⁻³ W
- 1 TR = 3516.852842067 W ÷ 0.001 W per mW = 3516852.842067 mW
Both units are defined exactly, so the factor is exact. Ton of Refrigeration definition: ton of refrigeration; Milliwatt definition: milliwatt.
Worked examples
- A reading of 2.5 TR converts to 8792132.105 mW.
2.5 TR × 3516852.842 = 8792132.105 mW - A value of 10 TR is 35168528.42 mW.
10 TR × 3516852.842 = 35168528.42 mW
