In the HP49 manuals, the way to convert units is explained as follows. For example to convert 12 m to ft (RPN):
12_m
1_ft
CONVERT
However as explained briefly in the HP48 guide, if you are not programming, it is much faster to go to the UNITS/LENGTH menu and type
12_m (type “12” and then “m” soft key)
LS ft (Left Shift and “ft” soft key)
Using RS (Right Shift key) units are divided.
I do not understand why this is not explained in the HP49 manual. I think you need to get the User’s Guide and the Advanced User’s Reference Manual of the HP48 to use all the resources of the HP49.
