About Converting Ton of refrigerations to Zettawatts
Ton of refrigeration and Zettawatt 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: Cooling power equal to 12,000 BTU/h, and zettawatt is 1e+21 watt units.
Formula
zettawatts = ton of refrigerations × 3.516853e-18
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 zettawatt equals 1e+21 base units, so dividing one by the other gives the direct ton of refrigeration-to-zettawatt factor of 3.516853e-18.
Simple example
1 TR × 3.516853e-18 = 3.516853e-18 ZW
1 ton of refrigeration = 3.516853e-18 zettawatts.
Real-world example
100 TR × 3.516853e-18 = 3.516853e-16 ZW
100 ton of refrigerations = 3.516853e-16 zettawatts.
