Refrigeration Tons to BTU/hr Converter

One refrigeration ton equals 12000 btu per hours (BTU/hr). To convert refrigeration tons to btu per hours, multiply by 12000; to go back the other way, multiply by 8.3333e-5 instead.

The converter above does it as you type and shows the working underneath, so you can check the arithmetic rather than take the number on trust.
