How to Convert BTU/hr to Tons of Refrigeration
To convert btu/hr to tons of refrigeration, multiply the power by the following conversion ratio: 0.000083333 tons of refrigeration/btu per hour.
Since one btu per hour is equal to 0.000083333 tons of refrigeration, you can use this simple formula to convert:
The power in tons of refrigeration is equal to the power in btu/hr multiplied by 0.000083333.
For example, here's how to convert 24000 btu/hr to tons of refrigeration using the formula above.
How Many Tons of Refrigeration Are in a BTU per Hour?
There are 0.000083333 tons of refrigeration in a btu per hour, which is why we use this value in the formula above.
Our btu per hour to ton of refrigeration calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
BTU/hr and tons of refrigeration are both units used to measure power. Keep reading to learn more about each unit.
What Is a BTU per Hour?
A btu per hour is a unit of power equal to 0.2930711 watts (W), the base unit for power. HVAC thermal rate (1 W ≈ 3.41214 BTU/hr). [1]
The btu per hour is classified as a US customary and imperial unit of power. BTU/hr can be abbreviated as BTU/hr; for example, 1 btu per hour can be written as 1 BTU/hr.
When working with btu/hr (BTU/hr) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, btu/hr (BTU/hr) are widely used across standard power applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
What Is a Ton of Refrigeration?
A ton of refrigeration is a unit of power equal to 3,516.8528421 watts (W), the base unit for power. HVAC cooling capacity equal to 12,000 BTU/hr or 3.51685 kW. [2]
The ton of refrigeration is classified as a US customary unit of power. Tons of Refrigeration can be abbreviated as TR; for example, 1 ton of refrigeration can be written as 1 TR.
When working with tons of refrigeration (TR) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, tons of refrigeration (TR) are widely used across large-scale industrial, bulk, and macro-level power specifications within US customary workflows, engineering documentation, and technical data sheets.
When converting power between btu/hr (BTU/hr) and tons of refrigeration (TR), keep full floating-point precision (1 BTU/hr = 0.000083333 TR; 1 TR = 12,000.0000071 BTU/hr) during intermediate calculations and round only the final ton of refrigeration figure to match your instrument tolerance.
