About Converting BTU per hour to Ton of refrigerations
BTU per hour 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: Power rate using BTU per hour, and cooling power equal to 12,000 BTU/h.
Formula
ton of refrigerations = btu per hour × 0.0000833333333333
This factor comes from each unit's defined relationship to the category's base unit: 1 btu per hour equals 0.293071070172 base units, and 1 ton of refrigeration equals 3516.85284207 base units, so dividing one by the other gives the direct btu per hour-to-ton of refrigeration factor of 0.0000833333333333.
Simple example
1 BTU/h × 0.00008333333333 = 0.0000833333 TR
1 btu per hour = 0.0000833333 ton of refrigerations.
Real-world example
100 BTU/h × 0.00008333333333 = 0.0083333333 TR
100 btu per hour = 0.0083333333 ton of refrigerations.
