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.

It's watts of _output_ that may be converted to horsepower; what manufacturers
provide is watts of _input power consumed_.

Shouldn't consumers insist on manufactureres providing output wattage
and HP? I am really sick of the seller getting away w/o having to
tpovide useful info.

I just don't believe in blind buying things via trial and error.

How much lobbying would it take to get such info printed?


Not all motors have the same
efficiency, and efficiency varies over a wide range. Without knowing that
efficiency, you have no idea how much power a motor is producing.

And then on top of that you've got the drivetrain losses, etc.
