HP 35s -> MILE / -> KM key Message #1 Posted by Stefan Vorkoetter on 3 Aug 2007, 1:40 p.m. I was just looking at the photos of the HP 35s in HP's brochure. Being a stickler for details, I immediately noticed that the "5" key, which has mile and km conversions on it, spelled "km" as "KM" (i.e. in capitals). Did they really do that, or is the calc in the brochure a mockup, and they fixed this blunder on the real thing?

Maybe that mean Kalvin Megabytes. Thats a new one to me. Interesting, that one mile equal 1.6093 Kalvin Megabytes. Im not even sure how one would interpret that. The temperature of one megabyte when traveling one mile is what it must be. See HP on cutting edge of new unit of measurement. :) Wonder if I need to put a degree symbol on it? :~)

I'm a bit confused by your statement. Did you mean SI? I thought a mole equals the atomic weight in g, so it would be just a pure number, not a unit. Or did you refer to the mere ontological existence ("IS") of the little, cute, furry animal digging under your lawn? In the latter case, you may need (estimated) 200 moles for 1 kg, i.e. 1 Kilo mole (as people would say here -- ou en francais: 1 kilo de ...) :-) Edited: 4 Aug 2007, 8:43 a.m.

Re: HP 35s -> MILE / -> KM key Message #7 Posted by Etienne Victoria on 4 Aug 2007, 2:18 p.m., in response to message #6 by Walter B Hello Walter, Yes I meant SI, sorry. And mole must be a quantity of matter (and I think it is a SI unit since 1972) because I have no garden & therefore no lawn ;-)) Cheers Etienne

Re: HP 35s -> MILE / -> KM key Message #8 Posted by Ed Look on 4 Aug 2007, 8:07 p.m., in response to message #7 by Etienne Victoria No, gentlemen: a mole, all jokes aside, is a number of objects, an Avogadro's number of objects, which, according to my HP-35s constants library is 6.02214199*10^23 objects. So if you take one group of this many objects and use it as a standard, then it could be considered a unit, just like twelve of anything is a dozen... or thirteen in bakeries... the good ones, anyway.

Re: HP 35s -> MILE / -> KM key Message #9 Posted by Walter B on 4 Aug 2007, 11:44 p.m., in response to message #8 by Ed Look Yes, gentleman: as stated above Quote: I thought a mole ... would be just a pure number Thanks for the confirmation.

Re: HP 35s -> MILE / -> KM key Message #10 Posted by Etienne Victoria on 5 Aug 2007, 4:56 a.m., in response to message #8 by Ed Look Yes gentlemen, I know very well it's the equivalent of a number but it is used as a SI unit along with the candela, km... as explained here. Many thanks for your answers and cheers. Etienne
