I generally leave my HP48 in the lab... so that leaves me using Google
Calculator all the time ;-) I'd forgotten that the HP48 is good with
complex numbers so I should probably start carrying it home...

Google Calc is useful in that it knows units, and it knows many the
fundemental physical constants... so you can do all sorts of cheating.


Throw this into the Google search box:

1/(2*Pi*4MHz*50 picofarads)

or try:

0.625*(c/14.030MHz) in feet
