Pretty much the same way you do other units.
Using the simplest example (length):
[Units] [Leng]
10 [enter]
[m] => (results in) 10_m on stack
1 [enter]
[in] => 1_in (in x register), 10_m (in y register).
[f] [UNIT.FCN] [Conv]
x: 393.7_in

Just make sure your units are compatible.
Farads are not convertible to Newton-meters per second squared.

Hope this helps!

This probably does not need saying in this venue, but I'll say it anyway.
(Unless you know tricks with the 42 that I don't -- which is pretty likely!) you have to understand the units you're working with. For example, if you have a simple 14 ohm resistive circuit and measure 12 amps going through it, E=IR gives you 168 volts, but Plus 42 will give you 168 amp-ohms, which you'd need to convert using the simple steps in my prior post. Same with simple resistive power, if you want P=EI and just entered 12_A x, you'll get 2,106_A^2*ohms, which you'd need to convert to watts.

Unless there's a trick that someone knows to get it to automatically reduce [funky] amp-ohms to [sane] volts, and so forth. I'm guessing there is one?
