Power Converter
Convert between kilowatts, metric horsepower (PS), imperial horsepower (hp), tons of refrigeration (TR).
Kilowatts
1,000.00kW
Metric HP (PS)
1,359.6PS
Imperial HP
1,341.0hp
Tons of refrigeration
284.345TR
Formula, assumptions, and limits
$$1 \text{ PS} = 735.49875 \text{ W}, \; 1 \text{ hp} = 745.69987 \text{ W}, \; 1 \text{ TR} = 3.51685 \text{ kW}$$
Main-engine sizing sheets often carry both PS (European builds) and HP (US/UK). Refrigeration compressor duty is commonly given in TR; air-conditioning duty in kW.
