I'm new to latex and trying to figure out the notation.

I'm trying to type out conversions, like (for example) 5 lbf * (4.4482 N / 1 lbf)= etc etc.

I'm not sure how to make the units show as units, or, at least, not as italics. I've seen how you can use \si{N}, but lbf isn't an SI unit, and I don't know how to combine \si with \frac.

    Hi, welcome. siunitx lets you declare new units, see e.g. tex.stackexchange.com/questions/27614/… Then if you've defined an \lbf unit, you can do e.g. \SI{4.4482}{\newton\per\lbf}. Note capital \SI which is for a number with a unit. – Torbjørn T. Feb 4 '19 at 20:19

    The siunitx package allows you to define your own units and typesets them in a consistent way. – Bernard Feb 4 '19 at 20:20
