About Converting Zeptowatts to Ton of refrigerations
Zeptowatt 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: Zeptowatt is 1e-21 watt units, and cooling power equal to 12,000 BTU/h.
Formula
ton of refrigerations = zeptowatts × 2.843451e-25
This factor comes from each unit's defined relationship to the category's base unit: 1 zeptowatt equals 1e-21 base units, and 1 ton of refrigeration equals 3516.85284207 base units, so dividing one by the other gives the direct zeptowatt-to-ton of refrigeration factor of 2.843451e-25.
Simple example
1 zW × 2.843451e-25 = 2.843451e-25 TR
1 zeptowatt = 2.843451e-25 ton of refrigerations.
Real-world example
100 zW × 2.843451e-25 = 2.843451e-23 TR
100 zeptowatts = 2.843451e-23 ton of refrigerations.
