Best compilation resource for all formulas and calculations

[1911]

I am looking for something I can carry with me in my work truck.
I am a trade school graduate who will be taking the J-man test soon. But my memory on the fly is not that great, I am good at math, never had a problem with it.

thanks.

I gave always included an Ugly's book in my reference library.

I also liked a pocket handbook that came from EASA (motor rewind shops) and a really old one from Shawmut fuses. I don't know if either if these are still printed.

I gathered my own for years and put everything I thought I would need into a Formulas spreadsheet.

Still adding but less I need.
