Physicists do this just fine. It's everyone else that uses it wrong. Go ask an auto mechanic how a battery works. They'll tell you that 'stuff' goes from positive to negative. Describing that electrons flow from the negative lead to the positive will make them look at you funny. Negatively charged particles come out of the negative lead. Makes sense to me!

They used to do this with the meter as well. There was a stick that was the definition of a meter. They then changed that definition after they found exactly what the speed of light was. Basically, it was 299,792,458.xxxxxx meters per second. I have no idea what the decimal was, but it doesn't matter anymore, because they redefined the meter as the distance light travels in a vacuum in 1/299792458ths of a second. Didn't change it much, but gave it an unwavering standard. You can use the meter and water to define a kilogram exactly, since another definition of the kilogram is the amount of water at STP (Standard Temperature and Pressure) that fills 1000 cubic centimeters. Reproducable anywhere without using the 'original' weight for measurement. Only real benefit of using a solid is that you can place it in a vacuum to eliminate any buoyancy caused by air. Still cool that they made such finely machined spheres.
