I don't know what platform you're using Plus42 on, so this next tip may or may not be so practical. On the 48 line of calculators you don't have to go through the the Unit's catalog to input units. You simply type an underscore and the symbol for the unit directly. e.g. 486_mm for millimeters or .486_M for meters.

Just a quick correction.
On hp50 (and 48, i suppose), the symbol for meter is "m", not "M".
As a matter of fact any operation using "M" fails with errore "invalid unit"

The information I've provided is correct for both 48GX and 50g as can be seen below:





Maybe Thomas altered things slightly for Plus42. But this seems unlikely, as he's always chosen HP UX conventions over modern conveniences in the past.

It must also be remembered that there are inconsistencies in the use of upper and lower case letters in the HP Units catalog due the the USA first aspect of HP Calculators - who new HP got there years before Donald J Trump (sorry couldn't resist being a Euro Socialist type!)

But there are many inconsistencies between SI conventions and the wider metric system from a lexigraphic perspective so "people in glass houses" and all that jazz.
