While that may be true, what is ultimately of importance is the power
delivered to the shaft of the motor. That is where HP and torque are
traditionally measured. What is better, a 15A motor with a 1.5 HP output or
one with a 1 HP output. Efficiency and power factor must be considered.
Input power is meaningless if you want to know how much work it will do.

HP "where the rubber meets the road" is of course the only meaningful
measurement. it's actually used in some high performance equipment,
but output brake horsepower is not something I've ever heard of being
measured on small electric motors. instead, the manufacturers seem to
be free to engage in whatever flights of fancy they please when
writing specifications.
