How to Convert Metric Horsepower to Ton of Refrigeration

Formula

Ton of Refrigeration = Metric Horsepower × 0.20913573

Worked Example

Example: 5 Metric Horsepower = 5 × 0.20913573 = 1.04567866 Ton of Refrigeration

To convert Metric Horsepower to Ton of Refrigeration, multiply the Metric Horsepower value by 0.20913573. This factor is derived from the ratio between the two units.

About These Units

Metric Horsepower

Metric horsepower (Pferdestärke in German, abbreviated PS) is a unit of power equal to approximately 735.5 watts. It is slightly less than mechanical horsepower (745.7 watts) and is used in automotive specifications in many European and Asian countries.

History

Metric horsepower was defined as 75 kilogram-force meters per second. The abbreviation 'PS' comes from the German 'Pferdestärke' (horse strength). It is widely used in Germany, Japan, and other countries for rating engine power. One PS equals approximately 0.9863 mechanical horsepower.

Ton of Refrigeration

A ton of refrigeration is a unit of power used in the HVAC industry, equal to approximately 3,517 watts or 12,000 BTU/h. It represents the cooling capacity needed to melt one short ton (2,000 lb) of ice in 24 hours.

History

The ton of refrigeration originated in the ice-harvesting industry of the 19th century. Before mechanical refrigeration, cooling capacity was measured by how much ice could be produced or consumed. A typical home central AC system is rated at 2-5 tons.
