Why people in the States still use those antique units is beyond me. Even the British now uses the ISO units. As for the google calculator, I'd better use a simple unit conversion program or some real calculators who can handle quite some units. Google Office, Google Map, Google xxx, Google yyyy, Google zzzzz, what is google now?

But some things still work. Gerhard -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
