Wattage is a measure of power and it is calculated from the motor's RPMs and torque measurments. Using horsepower units would result in rather small fractions, 1 HP = 746 watts, so when you are measuring small motors you at least end up with some numbers that are to the left of the decimal place. Two motors with the same watt rating could have very different RPMs and torque ratings, with different gears they could perform the same on the track.
