About Converting Kilowatts to Ton of refrigerations
Kilowatt and Ton of refrigeration both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Kilowatt is most often used for electric vehicle motor power ratings (alongside horsepower).
Formula
ton of refrigerations = kilowatts × 0.284345136094
This factor comes from each unit's defined relationship to the category's base unit: 1 kilowatt equals 1000 base units, and 1 ton of refrigeration equals 3516.85284207 base units, so dividing one by the other gives the direct kilowatt-to-ton of refrigeration factor of 0.284345136094.
Simple example
1 kW × 0.2843451361 = 0.2843451361 TR
1 kilowatt = 0.2843451361 ton of refrigerations.
Real-world example
100 kW × 0.2843451361 = 28.43451361 TR
100 kilowatts = 28.43451361 ton of refrigerations.

Reverse conversion: Ton of refrigeration to Kilowatt
0.2843451361 TR × 3.516852842 = 1 kW
0.2843451361 ton of refrigerations = 1 kilowatts.
kilowatts = ton of refrigerations × 3.51685284207

Understanding the Kilowatt
Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.
Where it's used: Standard power unit worldwide for larger appliances, vehicles, and electrical systems
Uses of the Kilowatt today
- Electric vehicle motor power ratings (alongside horsepower)
- Household electrical system and generator capacity
- Industrial motor and equipment power ratings
History of the Kilowatt
The kilowatt follows directly from the watt via the standard SI 'kilo-' prefix, becoming especially prominent with the growth of electrical power generation and distribution in the late 19th and 20th centuries.
Historical origin. Kilowatt was not the invention of a single named person; it developed through the process described above.
Understanding the Ton of refrigeration (TR)
Cooling power equal to 12,000 BTU/h.
Kilowatt — sources
- BIPM SI Brochure — SI prefixes — Defines 'kilo-' as the prefix for 10³.

Frequently asked questions
How many ton of refrigerations are in 1 kilowatt?
1 kilowatt equals 0.2843451361 ton of refrigerations, using the exact defined conversion factor rather than an estimate.
How do I convert kilowatt to ton of refrigeration?
Multiply the kilowatt value by 0.2843451361. The converter above does this instantly to whatever precision you set.
How do I convert ton of refrigeration back to kilowatt?
Use the reverse factor: 1 ton of refrigeration equals 3.516852842 kilowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilowatt?
Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.
What is a ton of refrigeration?
Ton of refrigeration (TR) is a unit of engineering.
Is the kilowatt to ton of refrigeration conversion exact?
Yes. Both kilowatt and ton of refrigeration are defined by fixed standards rather than physical artifacts, so the factor of 0.2843451361 used above is exact to as many digits as you choose to display.
Where is the kilowatt still used today?
Standard power unit worldwide for larger appliances, vehicles, and electrical systems
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
