conversion table for vacuum levels

I’m looking for a conversion table for different vacuum levels in mbar, in Hg, Torr and Pa. Not a table with formulas but one with values already calculated. I’ve seen one for pressure (Psi - bar) but I can’t find one for vacuum.

I’d prefer something I can just print and laminate to hang next to my pump.

Can someone post a download link?

Thanks.

Wightmarine, thanks.

After realizing the reason I wasn’t finding anything is because I was searching in German, I found several using the English search terms. Since my vacuum controller uses percentage of vacuum I wanted one with that at the front followed by mbar. I made the attached in Excel based on the formulas I found.

Since I’m working on a German computer the “,” and “.” exchange meanings so the “,” is a decimal point in the attached PDF.
