Convert from horsepower [international] to poncelet

Unit Definition (horsepower [international])
Horsepower (hp or HP) is the name of several non-metric units of power. In scientific discourse, the term "horsepower" is rarely used because of its various definitions and the already existent SI unit for power, the watt (W). However, use of the term "horsepower" persists as a legacy in many languages and industries, particularly as a unit of measurement of the maximum power output of internal-combustion engines of automobiles; and often of trucks, buses, and ships. The use of 'HP' is being slowly replaced by kW (kilowatt) and MW (megawatt).

Unit Definition (poncelet)
The poncelet is a unit of power formerly used in France but now obsolete. The poncelet is defined to be the power required to raise a mass of 100 kilograms at a velocity of 1 meter per second. This is equivalent to 980.665 watts or exactly 4/3 metric horsepower (1.315 traditional horsepower). The unit was named for the French mathematician and engineer Jean-Victor Poncelet (1788-1867). It was replaced in French engineering by the metric horsepower (cheval vapeur).
