About Converting Picowatts to Ton of refrigerations
Picowatt and Ton of refrigeration 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: Picowatt is 1e-12 watt units, and cooling power equal to 12,000 BTU/h.
Formula
ton of refrigerations = picowatts × 2.843451e-16
This factor comes from each unit's defined relationship to the category's base unit: 1 picowatt equals 1e-12 base units, and 1 ton of refrigeration equals 3516.85284207 base units, so dividing one by the other gives the direct picowatt-to-ton of refrigeration factor of 2.843451e-16.
Simple example
1 pW × 2.843451e-16 = 2.843451e-16 TR
1 picowatt = 2.843451e-16 ton of refrigerations.
Real-world example
100 pW × 2.843451e-16 = 2.843451e-14 TR
100 picowatts = 2.843451e-14 ton of refrigerations.
