One makes your neck hurt, the other makes you hit and see some serious shit. Torque being the force and horsepower being the rate at which that force is done. The difference is torque is doing the work, while horsepower is how fast that work is being done.
Horsepower, the common unit of power; i.s., the rate at which work is done. This value was adopted by the Scottish engineer James Watt in the late 18th century, after experiments with strong dray horses, each horse pushed with a force that Watt estimated at 180 pounds. From this, Watt calculated that one horsepower was equivalent to one horse doing 33,000 foot-pounds of work in one minute. It is actually about 50 percent more than the rate that an average horse can sustain for a working day.
