If you work with mechanical things, you must know this. Grabbing the wrong family of wrench or ratchet is frustrating. Know before you walk to your toolbox how to easily tell if you're dealing with a metric bolt and nut, or one that is inch (imperial) hardware.
As mentioned and shown in the video, here is a link to the FASTENAL Reference Guide that is a handy PDF. No affiliation, just sharing a good tool that I found on the internet in the past.
