About Converting Ton of refrigerations to Watts
Ton of refrigeration and Watt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Cooling power equal to 12,000 BTU/h, and the watt is one joule per second.
Formula
watts = ton of refrigerations × 3516.85284207
This factor comes from each unit's defined relationship to the category's base unit: 1 ton of refrigeration equals 3516.85284207 base units, and 1 watt equals 1 base unit, so dividing one by the other gives the direct ton of refrigeration-to-watt factor of 3516.85284207.
Simple example
1 TR × 3516.852842 = 3,516.852842 W
1 ton of refrigeration = 3,516.852842 watts.
Real-world example
100 TR × 3516.852842 = 351,685.2842 W
100 ton of refrigerations = 351,685.2842 watts.

Understanding the Ton of refrigeration (TR)
Cooling power equal to 12,000 BTU/h.
Understanding the Watt
Watt (W) measures power. The watt is the SI derived unit of power: one joule of energy per second. It is classified as a SI derived unit.
Where it's used: Standard scientific and everyday power unit worldwide
Uses of the Watt today
- Electrical appliance power ratings worldwide
- Light bulb brightness-equivalent labeling
- Engine and motor power specifications (alongside horsepower)
History of the Watt
The watt is named after James Watt, whose improvements to the steam engine in the late 18th century were commercially pivotal; ironically, Watt himself used horsepower (a unit he helped popularize) to market his engines. The watt was formally adopted as a unit at the 1889 General Conference on Weights and Measures and became the SI derived unit of power in the 20th century.
Historical origin. Watt was not the invention of a single named person; it developed through the process described above.
