HP Prime Fundamental Constants  Timothy Roche  12032013 All the fundamental constants in the updated software revision (5447) are correct to 12 significant digits (almost).
Minor quibble: f0 (the 1eVphoton frequency) is incorrectly rounded up in the constants library. f0=c/(lambda0)=c*e/h=2.417 989 349 604 730 E14So the value, rounded to 12 significant digits, should be: f0= 241 798 934 960 000 Thank you for the software revision and updating the constants,
Tim
Re: HP Prime Fundamental Constants  Tim Wessman  12032013 Picky, picky, picky. :P The units now show when you click VALUE. The only value that still isn't in "base" units is the value for StdP, but I've never once seen that given in anything but kPa. Thoughts? Any other constants you think should be added? TW

Re: HP Prime Fundamental Constants  Paul Dale  12032013 This constant definitely should be there :)

Re: HP Prime Fundamental Constants  Timothy Roche  12032013 I believe that most people using standard pressure will recognize its magnitude and the implied units if they are not displayed (with Value selected). Students in chemistry and physics will catch on quickly that the pressure units are kilopascals, too. The addition of the displayed units when Value is unselected is most welcome. If you are looking for more constants, the relative atomic mass of each element would be most convenient for student and professional alike. These may be easily found at the webelements page, which is authoritative and uptodate with the latest IUPAC values.

weeeell... since you asked... :P Or... what about adding a "user defined" item to the constant menus where anyone can store the constants we use more commonly (including their units of course)?

Re: HP Prime Fundamental Constants  CR Haeger  12042013 Yes please  a separate selection of user defined would be handy.

Re: HP Prime Fundamental Constants  Walter B  12042013 Personally, I wouldn't have chosen f_{0} and [lambda]_{0} to participate in this rather limited set of physical constants. Other constants come into my mind instead. YMMV
