To convert a value with units (8 m to ? mm) I need 21 steps by HP49G.
In RPN mode I must carry out by HP49G.
8;
arrow right;
minus;
alpha;
arrow left;
m;
Enter;
1;
arrow right;
minus;
alpha;
arrow left;
m;
alpha;
arrow left;
m;
Enter;
arrow right;
units;
OK;
OK;
RESULT 8000 mm.
Is that true? Or make I mistakes?

Sorry I can't really understand... do you use HP49G in RPN? If so converting
should be simple...
8
RightShift-6 (UNITS)
F2 (LENGTH)
F1 (m)
LeftShift-F3 (mm)
You have the correct result on the stack
Maybe I haven't understood the question.. if so my apologies... try to
explain in other words...

There is a simpler way. Just add 0mm to 8m to get the meters converted to
mm.
This trick works also for other consistent units.

Depends from which menu you start:
From menu other than "Units":
arrow right;
6 (activate "Units" menu);
LENG (softkey);
8;
M (softkey);
arrow left;
mm (softkey);
(answer displayed)
thats 7 keystrokes. Of course if your machine already displays the
units menu, your keystrokes would reduce to 4.
Dont get discouraged
Avoid reading the 49-manual on units! It simply omits (!) the really
ingenious unit handling from the 48 and makes a sophisticated story of
all this. With my small library Unitman (which, of course, sets the RPN
mode in case the user forgets it :-) you can convert what you want in
just one leftshift key-stroke. And you can quite easily customize the
whole builtin units system to an European setting (or
even a German one, with German names of Unit directories, say :-).
Moreover, you can eliminate these various square-miles etc (without
loosing them). Your own user-defined units are handled as if they were
builtin, i.e., you can convert them with leftshift like the builtin
units on the 48, but now on the 49!

PS. Unitman is available for both, the 48 and the 49

Hehe, good way to advertise your software.
Nice program by the way.
Is there something that can simplify (kg^2*m^4)/(A^3*s^6) to Wb/F without
thinking too much of what unit to convert to? Converting to SI base units
is easy, but sometimes trying to 'simplify' certain units proves difficult.
There has to be around this, no?

So I need 7 steps or in other words I must press the key for 7 times.
When I use the HP49G by RPN I don't understand your way.
1) 8; clear
2) RightShift; clear
3) 6 (UNITS); clear
4) F2 (LENGTH); I must go to Lenght by pressing key. It's the second in
the list
5) OK or ENTER;
6) M; I'm happy! it's the first in the list
7) OK or ENTER;
Now I have press the keys for 7 times and I in the middle of the
converting.
You wrote then:
LeftShift-F3 (mm) (You have the correct result on the stack)
I dont't undestand what you mean then, because after step 7) the unit
menü is closed.

Yes, there are several libraries for this on hpcalc.org:
SIunits by Rubén Pérez is excellent. It does a fully automatic job,
but cannot be configured. So if you want speciific outcomes for
specific units, it may or may not work. For your example above, it
works.
http://ca-on.hpcalc.org/details.php?id=1619
XUNITS by Luis Morales Boisset allows to set your preferred units, and
also tried combinations of these preferred units.
http://ca-on.hpcalc.org/details.php?id=4651
Utool is a library with many tools for Units. One of the
commands is USIMP which needs to be configured, but gives you full
control over the outcome.

There is also a UserRPL program for this task by John H Meyers

Hope this helps

My apologies... I assumed you use HP49 in soft-menu mode, flag 117 set.
Anyway I see you already fixed that....

Yes, 8m is 8000mm. You did not make a mistake.
Seriously, Nobody mentioned that you should set flag 117, "soft menu" to
restore HP48 softmenu key functionality. It should be intuitive from there.
Hope this helps,

Thank you for pointing out this overwhelming information.
It is much better being told what programs are convenient
for this task than searching and testing out many programs.
