I used to diss imperial units until I’ve started doing a lot of DIY and I can see some advantages using them. Everything is essentially always divided by two 1 inch, 1/2 inch, 1/4 inch etc, or by 1000 when very fine precision is required. You never get numbers that are hard to add up, divide or multiply when this especially comes into play when calculating derived units like PSI, clamping torque etc. And more importantly it makes calculating squares which are often used quite easy it’s much easier to square 3/16th of an inch than 4.7625.... mm Metric only really allows for easy conversion between magnitude of scale but when it comes to other calculations you get numbers which are hard to accurately calculate in your head and irrational numbers much more often than when using imperial units. And irrational numbers can’t be measured. It’s very easy to make a measurement tape that does 1/16th of an inch increments and measuring 3/16th of an inch is a breeze measuring 4.76251784744823823... mm on the other hand is eyeballing it.
