Original GitHub issue: https://github.com/UpsilonNumworks/Upsilon/issues/272

The foot, pound, second units of measure missing from the available options are as follows,
The pound force (lbf) defined as a pound times the standard gravity or exactly 4.4482216152605 N.
The slug (slug) defined as lbf s^2 ft^-1 or exactly 8896443230521/609600000000 kg.
The pound per square inch (psi) defined as lbf in^-2 or exactly 8896443230521/1290320000 Pa.
While they may be somewhat obscure, they are still very much in use so I hope it wouldn't be too much of a bother to add them to the list.

@Overengined commented on GitHub (Mar 5, 2023):

Slug and Pound Force wouldn't make a lot of sense in my opinion because they all got replaced officially by a standardised metric equivalent. However, psi is still used on a lot of pressure gauges around the world, so I guess it would be interesting to add it for practicality because because of its wide usage.
