HP49G Unit Conversion  Mike  03012000 Does anyone know of a quick way to convert units on the HP49G? Under the HP48 series I could simply do the following: 1) select the UNITS key 2) select the catagory 3) enter the numberportion of the units to convert from followed by the convertfrom unit softkey. 4) press the leftshift key followed by the convertto unit softkey to perform the conversion. Under the HP49G, steps 13 are similar. However after that I must do the following: 4) enter 1 (or any number) followed by the UNITS key, catagory key and then the convertto unit (essentially 2 items are now on the stack). 5) Press rightshift/UNITS/TOOLS/CONVERT to perform the conversion. Hmmm?!?!?! Steps 4 and 5 for the HP49G seem to add conciderably to simply converting from one UNIT to another. Is there a shorter way? (Entering the UNITS objects by hand into the stack seems to me to be even more laborious). Thanks tons in advance! Mike
Re: HP49G Unit Conversion  erwin  03022000 after you put the unit and its value to be converted on the stack,pres leftshift and the unit,from the menu, to wich you want it to convert.this ends the convertion. I hope it's clear.
Re: HP49G Unit Conversion  Mike  03082000 Thanks Erwin However, I'm not clear on what you've mentioned. I enter the following keysequence from what I understand from your response... (let's convert 1 KNOT to MPH (miles/hr.) for example). 1) Place 1 onto stack 2) Rightshift then 6(Units key). In menu highlight 6(Speed) then F6(OK). In next menu highlight 6(Knot). Press F6(OK). 3) 1._knot is on the stack. 4) Where do I go from here (Exact keys to press)? I attempted to proceed as follows... A) Rightshift then 6(Units key again). In menu select 6(Speed again) then F6(OK). In next menu cursordown to highlight 5. mph and then I leftshift followed by F6(OK). Hmmm?!?! Just beeps at me. Could you clarify with keysequence perhaps? Thanks again tons Erwin. Mike
Re: HP49G Unit Conversion  r. d. bärtschiger.  03092000 Hi Mike, The proper sequence for converting units on the hp49g & also the 48 series is as follows, press keys in exactly this order: Using your example of converting knots to mph. this assumes the calculator is in rpn mode. 1 right shift minus to place an underline after the one, (press * on 48) right shift 6 to access the units menu f6 for speed units, (press e on 48) f6 again, to place knot after 1_, (press f on 48) ENTER left shift mpg to convert to mph Hope this helps. rdb.
Re: HP49G Unit Conversion  erwin  03092000 Sorry for my unaccurate way of explaining how to convert on the 49. R.D. Bärtschiger did a better job,and it was close to what i meant. I read the first chapter of Mike’s mail d.d 03012000,that state's how to convert on the 48. I performed it on the 49,and it work's. And need’s a few keystroke’s less then Bärtschiger’s methode. This is how i did it. Let's see how many gram there are in one kilogram. The calc has the stack (RPN mode) menu active now. Calc is in RPN. 1: press rightshift than units. Press next and choose mass,F1. 2: press Kg,F1. The beep sounds and the box 'Error Too Few Arguments' appears on the screen. Just press on/cancel and the box disappears, leaving 1._kg on the stack. 3: press leftshift,then choose g from the menu,F2. Kg is now converted to grams To convert 2 Kg to g: 1: press rightshift than units. Then press next and choose mass,F1. 2: press 2 than Kg,F1. 3: press leftshift than g,F2 (gram). It say's 2000._g on the stack. Erwin
