I can actually do all of those in my head, so that wouldn’t be an issue for me.
But yeah, all of my tools and bits and holders are imperial, and someone else better be paying to get the damn things replaced or they are staying imperial even if we go metric. I think the only things I have in metric are allans (allens? I’ve never had to spell it out), like 2 hole saws from an old project, and a set of calipers I was gifted and have used maybe twice
Do we really need them here though? Do we even want them here?
