Looking into the ReM is highly recommended: whatever is marked green should work - everything else doesn't yet.

... and reduce the number of assumptions a user must make. Less freedom. Bad, bad, I admit ... !

Re: Who uses the 43S simulator under Windows, Linux, or on a Mac?
Hi,
I have been playing a bit with the WP43S PC emulator that works great , thanks !
First thing as my usual calculator bench, I tried unit conversions menu under the "f6" "U->" key.
And i did not found some quite usefull conversions for mechanical guys :
psi <=>bar (needs to convert first to atm or Pa) ;
lbf⋅ft <=> N.m ;
Of course , i invested long ago into a digital Torque wrench and some air pumps with digital gages (low and high pressure).
Tools that can be switched between Imperial and IS units on the push of a button...
But wouldn't it be a nice feature to get those conversions right into the ultimate RPN calculator ?

Re: Who uses the 43S simulator under Windows, Linux, or on a Mac?
Thanks for your thoughts. Fundamental rule in our menu of unit conversions is that each conversion begins or ends in an SI unit.
Thus the conversion psi->Pa. And almost every mechanical guy knows by heart that 1 hectopascal equals 1 millibar, but if in doubt you can call (after psi->Pa) Pa->bar and you're done. Two simple keystrokes after calling the F&p submenu. Hard to imagine anything shorter.
About torque conversions: Press N->lbf EXIT [x:] [f] m->ft. and you're done. Five keystrokes after calling the F&p submenu. Hmmh. Could be done quicker with 'Nm<->lbf ft' located in the second view of U-> between the two dB conversions. Will think about it.
(Edit: Consider 'Nm<->lbf ft' being implemented.)

I think part of the calc usability would be that a unit on the gauge in front of you would be available for conversion, whether it starts and/or ends in SI units or not, and that would include commonly used SI multiplied units, such as km and g. (I mean, some know there are 5280 ft to the mile, and you don't expect the those folks to multiple or divide by 5280, but we must multiply or divide continuously with 1000 or 100 )
Also, I think that the unit conversions may form an excellent use case for your catalog browser, in addition to the shortcuts menus. (But programming that is beyond my capabilities!)
I once (2020-01-03) asked (elsewhere) for mm.Hg <> Pa and Walter, you said "...we have mm.Hg in our portfolio already! 1 mm.Hg = 1 torr !".Thus the conversion psi->Pa. And almost every mechanical guy knows by heart that 1 hectopascal equals 1 millibar, but if in doubt you can call (after psi->Pa) Pa->bar and you're done. Two simple keystrokes after calling the F&p submenu. Hard to imagine anything shorter.
However, this is not true. It is true that it is in the portfolio, but the equality is not:
The torr is defined as 1/760 of one standard atmosphere, while the atmosphere is defined as 101325 Pa. Thus, 101325/760 = 133.3223684210526315789473684210526315789473684210526315789... Pa.
The 43S gives 1 Torr to be 133.3223684210526315789473684210526 Pa. This is correct.
The millimeter of mercury by definition is 133.322387415 Pa (13.5951 g/cm3 × 9.80665 m/s2 × 1 mm).
The 43S gives 0.001 [m > in.] [in.Hg > Pa] > 133.3223684210526315789473684210526 Pa
This factor is incorrect because you assume 1 mm.Hg = 1 Torr, which it is not (any more).
Source
So, I am glad to say that due to the unique conversion factor [mm.Hg <> Pa] does deserve a place in the 43S. That is, despite my opinion that even if it had been the same, that it still would deserve place due to some people and/or equipment using it.
So this is my plea to request mm.Hg <> Pa again!
Edited for a 1000 factor being incorrect

About two outdated pressure units, please allow me quoting the English Wikipedia where you can expect some understanding for such units:
Anybody who does precision pressure measurements (meaning 3-digits precision and more) will use pascals or millibars directly - and owns the respective gauges, properly calibrated of course.
The key field of application of mm.Hg is medicine. I'm sure no physician or physiologist will ever object if I declare 1 mm.Hg equals 1 torr for them (these people are very content with % accuracy generally - they have other problems to solve).One millimetre of mercury is approximately 1 Torr, which is 1/760 of standard atmospheric pressure (101325/760 ≈ 133.322368421053 pascals). Although the two units are not equal, the relative difference (less than 0.000015%) is negligible for most practical uses. ... The precision of modern transducers is often insufficient to show the difference between the torr and the millimetre of mercury.

Re: Who uses the 43S simulator under Windows, Linux, or on a Mac?
Engineers (like me), not unlike the physicians you claim, should need no more than 2 digits in our 43 devices, but I like the calculator's accuracy regardless. Even though I also have other problems to solve, just last week, I had to increase the internal digits to 75 digits to get a reasonable 30+ digit accuracy on your new 43S function ln(1+x). So accuracy is important to me at least. I will fix my own [mm.Hg>Pa] inaccuracy because I want it right, not because I need to use all the digits for my gauges and charts. You do with yours what you likeWalter wrote: ↑Wed Jun 17, 2020 10:58 pmAbout two outdated pressure units, please allow me quoting the English Wikipedia where you can expect some understanding for such units:The key field of application of mm.Hg is medicine.
