I know we are not supposed to talk politics here, but I do think this is bit relevant to the Metric vs Imperial system. Jon, if you wish to delete this, I will not be offended.

We are in this metric vs imperial situation all due to politicians. https://www.thefactsite.com/imperial-metric-facts/

I simply live my life, use what tools I have to do what I need to do. I am comfortable using either system. To me they are simply a different language. I was raised speaking English. I also know a little, very little, Spanish, French and Haitian Creole from some mission work I have done in the past. Neither of those is wrong, just different andI know one A LOT better than the other three.

I can measure in both and have both to measure with. I have a great number of precision measuring tools that belonged to my father. Some from the 1930's. I learned a lot from him and miss him a lot. Someone suggesting that I throw them out, even if I do respect the person, is not going to sit well with me.

Let's all use the system we are comfortable with and not criticize. Nothing we say here is going to change the fact there is more than one measuring system.
