It won't make a difference to anyone not doing serious precision measurem ents but it looks like the 70+ -year-old definition for the Ampere is final ly going to be formally tied to the number of electrons going by per second rather than the hypothetical (so far experimentally unmeasurable) force be tween two parallel conductors:
Of course, it will rely on lab techniques that aren't quite nailed down y et but they seem to think it can be done on an easily-replicated "NIST on a chip" by 2018
I don't expect to need to go get my Fluke DVM recalibrated, or to see mas s recalls of consumer electronics...
Anyone here going to be directly affected?
