First, I'd say that you probably want to invest in your IDE or editor. But more important: there's middleground. What about setSpeedMmps() if setSpeedInMillimeterPerSecond is too noisy. My ROT is that the unit or type designation schould not overshout the most important info. Which, in case of setSpeedInMillimeterPerSecond is arguably, indeed the case. But the solution is almost never binary, but a more succint version. Everyone understands km, mm, sec, hr (though the win with such is silly) px and so on.
