Sure they do, since Watts is directly converted to horsepower: 749 Watts
is 1 horsepower. In the case of a food processor, you'll only have the
few % losses in the gearbox to derate it from the advertised wattage to
useful work. Given the supply voltage, the current drawn, and the power
factor or the load you can work out how much energy is going into that
appliance to be converted to useful work.

Maybe you mean torque (foot pounds or Newton metres) as the important
non-provided information. A graph of torque vs speed may be useful to
work out where your appliance does its most efficient work, or if it
even suitable for some tasks.
