Horsepower (Metric) to Tons of refrigeration converter

To convert horsepower (Metric) to tons of refrigeration, enter the value in the first field. The result in tons of refrigeration is calculated automatically using the exact conversion factor.

1 metric hp ≈ 0.209135492166 TR
1 TR ≈ 4.78158914895 metric hp

Formula: TR ≈ metric hp × 0.209135492166
metric hp ≈ TR × 4.78158914895

Definitions: 1 metric hp = 735.49875 W; 1 TR = 12000 BTU/h

The metric horsepower (PS in German, CV in Spanish, ch in French) is 75 kilogram-force meters per second, exactly 735.49875 watts, about 1.4% smaller than the mechanical horsepower. It is used for engine power in Europe and much of Asia.

The ton of refrigeration (TR) is 12,000 BTU per hour, about 3.517 kilowatts, originally the cooling produced by melting one short ton of ice in 24 hours. It is used to rate the capacity of air-conditioning and chiller systems.
