With the metric system widely used today , would a Spanish Galion of old now be a Spanish 3.79 liter?

Spain is a big winemaking country, so they would use standard sizes, like 0.75 liter or 1.5 liter. With centuries of inflation, government spending, and manufacturers reducing package sizes to boost profits, I would have to go with the 0.75 liter size.

Edit:

OK, so you think my sense of humor is as weak as yours. Well, if you want something funnier, you are going to have to start with a stronger opening!

I think you are confusing the Spanish Galleon, which is a sailing ship that transfered goods from the West Indies to Spain during the 1500's, with the volumetric measurement gallon.

Galion? do you mean gallon?

there are many many different definitions of gallon. The one you seem to be thinking of is:

the wine gallon, or “Queen Anne’s gallon”, which was 231 cubic inches (≈ 3.79 L)

But what is your question?
