Yeah, me too G.
Keltin's usage might date back to the old days, when people mostly made their own butter. On fancy tables it was made in molds. But in most households it was just patted into a round shape.
On average, a churn yielded a pound of butter at a time. So a "pat" could have come into usage to describe the final product.
Outside of the U.S., butter is always packaged, sold, and used by weight. But that applies to a lot of things we do by volume.
