About Converting Ton of refrigerations to BTU per hour
Ton of refrigeration and BTU per hour both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Cooling power equal to 12,000 BTU/h, and power rate using BTU per hour.
Formula
btu per hour = ton of refrigerations × 12000
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 btu per hour equals 0.293071070172 base units, so dividing one by the other gives the direct ton of refrigeration-to-btu per hour factor of 12000.
Simple example
1 TR × 12000 = 12,000 BTU/h
1 ton of refrigeration = 12,000 btu per hour.
Real-world example
100 TR × 12000 = 1,200,000 BTU/h
100 ton of refrigerations = 1,200,000 btu per hour.

Frequently asked questions
How many btu per hour are in 1 ton of refrigeration?
1 ton of refrigeration equals 12,000 btu per hour, using the exact defined conversion factor rather than an estimate.
How do I convert ton of refrigeration to btu per hour?
Multiply the ton of refrigeration value by 12000. The converter above does this instantly to whatever precision you set.
How do I convert btu per hour back to ton of refrigeration?
Use the reverse factor: 1 btu per hour equals 0.0000833333 ton of refrigerations. You can also use the swap control in the converter above to flip the direction instantly.
What is a ton of refrigeration?
Ton of refrigeration (TR) is a unit of engineering.
What is a btu per hour?
BTU per hour (BTU/h) is a unit of engineering.
Is the ton of refrigeration to btu per hour conversion exact?
Yes. Both ton of refrigeration and btu per hour are defined by fixed standards rather than physical artifacts, so the factor of 12000 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
