I bet you didn't know that the US weight of a lb is actually based on its percentage weight relative to the US standard of a 1kg standard weight. So the US standards (for weight anyway) are actually metric. See this for an explanation -

Very interesting footage! For most of us, it remains certainly "anecdotic", but for scientists who play with milligramms, nanometers and the like, this is important, even if the key is "difference" between the "master sample" and the replica. Ah...finally something astonishing (for me quite incredible!) to share with friends while having a glass in a bistrot. Thanks a lot for sharing the "NEWS of the Year!

I think I'd seen something along these lines before but that was more interesting without going into to too much technical detail.
Reminded me of my Apprenticeship days when we were changing, for example, 15/64" to 5.862mm.

Now, where can I get a Bootie Butler?

I have just watched the video from the same guy where he shows the work happening to define the weight using physics instead of an actual physical block of material. I have to admit I did not follow the math too well. But I could see why they would want to do it because the 2 dozen odd weights that are compared back to the master weight are now varying very slightly from each other.
And I was very impressed by the Bootie Butler. Every crime scene needs one of these.

I'm old, but have been using both imperial and metric for many years. I guess I'm bi-systemic.

I too grew up with Imperial and still mostly use it because it is embedded in my mind.
But I find 37/64ths a bit difficult to measure, metric is so much easier to use.
Calculations with metric are so much simpler.

Don't they have medicine for that? 😁
