Wine & Spirits vocabulary: Quick and Easy Chart of size and volume (and name) conversion from the US System to the Metric System

In the US, where the metric system isn't fully used, integrated or even understood, despite the number of citizens and immigrants using it everyday, it is sometimes difficult to spontaneously convert sizes and other measurements, especially when faced with a situation where both persons say the same thing but in fact have no idea what the other one is saying.

When I first arrived in the US, in 2002, very often at the store, customers asked me for “pints” or “quarts” or a "gallon", and I need to admit that it took me a bit of time to get acquainted with the different sizes and names. When you've grown up all your life using it, it is easy, yet even some American that I know still have no clue. I was even asking my wife to help me to comprehend that new system, which was quite intriguing for a European guy like me.

Since then, I learn how to spontaneously convert things in my head, but it took me a few years to get to that point. Therefore, and because I think that I’m not the only person facing that problem, here is a quick and easy chart, to help you every time you need to.

This short chart is by no mean exhaustive and I'm sure that I could have add plenty of other things... but, hey, that's an helpful start!
