I have the 'calculator that takes no prisoners' the HP 48. It is big
enough to fit a hand, and the keys are far enough apart. It has the
conversion from HP to watts, and lots more. Highly recommended if you
like to post on technical matters. [1 HP equals 745 watts]..

Time to get that '48 calibrated, 1 Hp = 745.69987, even if you round it
to three significant figures you 746. (I know, nitpicking)
