About Converting Nanowatts to Ton of refrigerations
Nanowatt 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. Specifically: Nanowatt is 1e-9 watt units, and cooling power equal to 12,000 BTU/h.
Formula
ton of refrigerations = nanowatts × 2.843451e-13
This factor comes from each unit's defined relationship to the category's base unit: 1 nanowatt equals 1e-9 base units, and 1 ton of refrigeration equals 3516.85284207 base units, so dividing one by the other gives the direct nanowatt-to-ton of refrigeration factor of 2.843451e-13.
Simple example
1 nW × 2.843451e-13 = 2.843451e-13 TR
1 nanowatt = 2.843451e-13 ton of refrigerations.
Real-world example
100 nW × 2.843451e-13 = 2.843451e-11 TR
100 nanowatts = 2.843451e-11 ton of refrigerations.

Frequently asked questions
How many ton of refrigerations are in 1 nanowatt?
1 nanowatt equals 2.843451e-13 ton of refrigerations, using the exact defined conversion factor rather than an estimate.
How do I convert nanowatt to ton of refrigeration?
Multiply the nanowatt value by 2.843451e-13. The converter above does this instantly to whatever precision you set.
How do I convert ton of refrigeration back to nanowatt?
Use the reverse factor: 1 ton of refrigeration equals 3.516853e+12 nanowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanowatt?
Nanowatt (nW) is a unit of engineering.
What is a ton of refrigeration?
Ton of refrigeration (TR) is a unit of engineering.
Is the nanowatt to ton of refrigeration conversion exact?
Yes. Both nanowatt and ton of refrigeration are defined by fixed standards rather than physical artifacts, so the factor of 2.843451e-13 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.
