Watt determined that a horse could turn a mill wheel 144 times per hour, which he calculated as 33,000 foot-pounds per minute, creating the unit to demonstrate engine power.

His separate condenser kept the cylinder hot, avoiding energy loss from repeated heating and cooling. This cut fuel consumption by roughly 75%, making steam power far more practical and economical.

Watt invented the centrifugal governor himself; Boulton was the financier and business partner, not the engineer.
