I have to agree with growlf
on this: A "metric buttload" is a unit of measurement of which I was not aware, but clearly should have been. Can we get some more detail on this? Is this a unit of volume or mass? Is the NIST aware of it and do they have a gold standard for it in their possession? (That's quite a mental image, isn't it?)
Well, depending upon the price, I probably can't afford a metric buttload of PM mugs, but if you will sell them in other units sign me up for a metric centibuttload of them.
