horsepower (cheval-vapeur)
Symbol:  cv, HP 
Category:  Power (Heat flow) 
SI Equivalent:  735.499 W
Dimension:  ML2T-3 
 
Notes
Unit of power introduced by James Watt in 1782. It is equal to the power needed to raise 528 ft3 of pure water by 1 meter in 1 minute. The final conversion factor was adopted in 1850 as:
1 HP (cheval-vapeur) = 75 kgf-m/s
Convert     cv, HP
