Because in our free market economy we use units to create deception. The best example given is the preferred pricing per pound because the pound price appears cheaper.
Horsepower is preferred over kilowatts because horsepower numbers are larger and give the illusion of having more power. A 15 000 BTU air conditioner seems more powerful then a 4 kW model, even though they are the same. Single units also allow for easy comparison, which is what industry wants to avoid. you want to deceive your customer into thinking your product gives more for less when with single units, that may not appear so.
