Seems like it would be easier to buy a metric rule than constantly converting. I have rules and tapes in inches, metric, and tenths of an inch; they all come in handy. Earlier my daughter needed a bunch of stuff cut and the parts list was in tenths, 1.83”, 1.71”, etc. No trouble at all.

Apologies to the OP for the hijack. I have an architects rule that I haven’t used in 30 years and I was a chemistry major so have no problem with the math or conversions. My issue is that I am a 60 year old American curmudgeon and my brain is calibrated to imperial. If you tell me it’s 37C outside I have no reference but I know what 98F feels like. My table saw fence is in inches, my router lift is in inches as well as almost everything else I measure or cut with so I convert back to inches most of the time. Lumber stores here are starting to measure thicknesses in mm so I do know that 3mm plywood fits in an 1/8th inch groove.

I remember back in the 70’s we were going to switch to metric and were ready to bite the bullet but unfortunately it just never happened.

Then there’s the Brits. A boxer weighs 12 stone 4 at the weigh in? WTF is that?! :-) Is a lid still 3 fingers?
