Metric is the best stand by we have devised. Back in the ye old times you actually had a master weight on stand by to determine what a pound was and then you made copies of said master weight so everyone was on the same page to what weighed what.
There were several kilo master weights until recently when it was determined that a kilo would just be a cylinder of platnum so a kilogram would officially be like a bazillion platnum atoms. making the measurment of a kilogram just as accurate as a meter.
Do you prefer the metric system or the imperial system?
