About Converting Ton of refrigerations to Microwatts
Ton of refrigeration and Microwatt 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 microwatt is 0.000001 watt units.
Formula
microwatts = ton of refrigerations × 3516852842.07
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 microwatt equals 0.000001 base units, so dividing one by the other gives the direct ton of refrigeration-to-microwatt factor of 3516852842.07.
Simple example
1 TR × 3516852842 = 3,516,852,842 uW
1 ton of refrigeration = 3,516,852,842 microwatts.
Real-world example
100 TR × 3516852842 = 351,685,284,200 uW
100 ton of refrigerations = 351,685,284,200 microwatts.

Reverse conversion: Microwatt to Ton of refrigeration
1 uW × 2.843451e-10 = 2.843451e-10 TR
1 microwatt = 2.843451e-10 ton of refrigerations.
ton of refrigerations = microwatts × 2.843451e-10

Frequently asked questions
How many microwatts are in 1 ton of refrigeration?
1 ton of refrigeration equals 3,516,852,842 microwatts, using the exact defined conversion factor rather than an estimate.
How do I convert ton of refrigeration to microwatt?
Multiply the ton of refrigeration value by 3516852842. The converter above does this instantly to whatever precision you set.
How do I convert microwatt back to ton of refrigeration?
Use the reverse factor: 1 microwatt equals 2.843451e-10 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 microwatt?
Microwatt (uW) is a unit of engineering.
Is the ton of refrigeration to microwatt conversion exact?
Yes. Both ton of refrigeration and microwatt are defined by fixed standards rather than physical artifacts, so the factor of 3516852842 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.
