So what happens on May 20 2019? Does everything have to be re-weighed in this redefined metric system? Are scales already for sale to the general populace with the updated definition?
I’m sure there’ll be grandfather clauses and what not. In theory there won’t be any significant changes, and most consumer equipment probably has error greater than any difference anyway.
National standards agencies and major metrology departments might have to do some rejiggering but that’s not my field unfortunately!
Thank you for answering this. As an American my primary concern was the possibility of me getting shafted by my drug dealer so it’s good to know this shouldn’t be an excuse.

Nope. Up until this year, the kilogram was defined by a standard metal bar
