Convert Horsepower (metric) to Ton (refrigeration)

Please provide values below to convert horsepower (metric) to ton (refrigeration), or vice versa.

From: horsepower (metric)
To: ton (refrigeration)
     

Horsepower (metric)

Definition: The unit horsepower (symbol: hp) is a unit of measurement of power (the rate at which work is done). Mechanical horsepower, also known as imperial horsepower, is defined as approximately 745.7 watts (550 ft·lbf/s), while metric horsepower is approximately 735.5 watts (75 kgf·m/s). Boiler horsepower, albeit a less common measurement than either imperial or metric horsepower, is used for rating steam boilers, and is equivalent to 34.5 pounds of water evaporated per hour at 212 degrees Fahrenheit, or 9809.5 watts. In addition, when rating electric motors, one horsepower is equal to 746 watts.

History/origin: The term horsepower was adopted in the late 18th century by James Watt to compare the output of steam engines with the power of draft horses. Watt was not the first person to compare the output of horses to that of engines. As early as 1702, Thomas Savery referenced horses when describing the output of an engine. It is believed that Watt built on this idea and introduced the term horsepower, largely in an effort to market his steam engine. The term was later expanded to include other types of output power such as the imperial and metric horsepower measurements commonly used today.

Ton of refrigeration

Definition: A ton of refrigeration (TR) is a unit of power. It is defined as the power required to melt or freeze 2000 pounds, also known as one short ton, of ice per day. The ton is more often a unit of mass. A ton of refrigeration is approximately equal to 12,000 BTU/h or 3.5 kW.

History/origin: The ton of refrigeration originated around the 1880s during the transition from stored natural ice to mechanical refrigeration. It became an industry standard in 1903 when Thomas Shipley pushed for the formation of an industry association as well as for standardization of a number of equipment specifications. This eventually led to the founding of the American Society of Refrigerating Engineers in 1904.

Current use: The ton of refrigeration is mostly used in North America, specifically within the context of refrigeration and air conditioning equipment. It is often displayed alongside BTU/h specifications.
