About Converting Ton of refrigerations to Terawatts
Ton of refrigeration and Terawatt 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. Specifically: Cooling power equal to 12,000 BTU/h, and terawatt is 1000000000000 watt units.
Formula
terawatts = ton of refrigerations × 3.516853e-9
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 terawatt equals 1e+12 base units, so dividing one by the other gives the direct ton of refrigeration-to-terawatt factor of 3.516853e-9.
Simple example
1 TR × 3.516853e-9 = 3.516853e-9 TW
1 ton of refrigeration = 3.516853e-9 terawatts.
Real-world example
100 TR × 3.516853e-9 = 3.516853e-7 TW
100 ton of refrigerations = 3.516853e-7 terawatts.

Frequently asked questions
How many terawatts are in 1 ton of refrigeration?
1 ton of refrigeration equals 3.516853e-9 terawatts, using the exact defined conversion factor rather than an estimate.
How do I convert ton of refrigeration to terawatt?
Multiply the ton of refrigeration value by 3.516853e-9. The converter above does this instantly to whatever precision you set.
How do I convert terawatt back to ton of refrigeration?
Use the reverse factor: 1 terawatt equals 284,345,136.1 ton of refrigerations. You can also use the swap control in the converter above to flip the direction instantly.
What is a ton of refrigeration?
Ton of refrigeration (TR) is a unit of engineering.
What is a terawatt?
Terawatt (TW) is a unit of engineering.
Is the ton of refrigeration to terawatt conversion exact?
Yes. Both ton of refrigeration and terawatt are defined by fixed standards rather than physical artifacts, so the factor of 3.516853e-9 used above is exact to as many digits as you choose to display.
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.
