Convert from clusec to horsepower [international]

Unit Definition (clusec)
The clusec is a unit of power used to express the performance or leakage of vacuum pumps. One clusec represents a flow of 10 milliliters per second at a pressure of one micrometer (or micron) of mercury. This is equivalent to 0.01 lusec or 1.333 microwatts. The name of the unit is an acronym for "centi-lusec."

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).
