There's a web app for the Chrome browser called "Chromey Calculator" that I like. Last thing I typed into it was "50 ft-lb * 10 rpm in watts =3D" and it answers: 70.99 W (watts) The other one that was nice "100nC *20000Hz in amps =3D" 0.002A Those are fairly messy calculations otherwise. -Denny --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
