Tons of Refrigeration and horsepower are both units used to measure power. Keep reading to learn more about each unit.
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. [1]
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.
What Is a Horsepower?
A horsepower is a unit of power equal to 745.6998716 watts (W), the base unit for power. Imperial mechanical horsepower (550 ft·lbf/s ≈ 745.7 W). [2]
The horsepower is classified as a US customary and imperial unit of power. Horsepower can be abbreviated as hp; for example, 1 horsepower can be written as 1 hp.
When working with horsepower (hp) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, horsepower (hp) are widely used across standard power applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
When converting power between tons of refrigeration (TR) and horsepower (hp), keep full floating-point precision (1 TR = 4.7161773 hp; 1 hp = 0.2120361 TR) during intermediate calculations and round only the final horsepower figure to match your instrument tolerance.
