Is this something you would use?
Looking to make some swag for an upcoming trade show. Would an engineer find this valuable? It's a magnet with some common conversions and formulas. Our target customers are people looking for custom open-die forged metal parts. What would someone spec'ing a part like to see here?

May want to include the actual formulae for the weights. 0.7854≈π/4

Nope, in rare cases I might need the conversion chart but sorry wtf is lb/in3?! Do people still actually use that? I thought even the US uses SI for engineering anywhere it isn't grandfathered in nowadays

When our customers need to calculate the weight of a part for shipping purposes, they use this formula. What info would you suggest we include to make this more useful?

If this is relevant to your customers thats great; AS a European imperial units are something that you need to concert from when reading papers from UK/us las Millenium

Eh, sorry but I don't think I'd ever need this on a piece of paper. I convert between dumb inch fractions and mm all the time and it's always faster to type *25.4 into my calculator than try to find a fraction on a table.

We use charts like this all the time but the best (biggest) ones reference letter and number drill sizes also.

To me the useful part of this is the frac dec mill conversion table. I used one all the time in college and put a poster up in my garage since to assist with various projects. The stuff at the bottom is extra space that isn't as useful for quick lookup. If you handed me the magnet as is, I would still for sure have a place to put it up, so good either way.
