Metric vs. other measurement systems - chart

Great, do you also have one for weight and volumes?

A volume chart is going to be messy. Just the "barrel" unit alone will have a forest of intertwined lines like a French hedgerow.

There are seven different barrel sizes used in the USA, with the size being dependent on the contents. Their names and metric equivalents are as follows: US cranberry (95.5 liters), US dry (115.628 liters), US liquid (119.24 liters), US federal (117.348 liters), US federal proof spirits (151.416 liters), US drum (208.4 liters), US petroleum (135 kg.), US petroleum statistical (158.99 liters).

And then there's the matter of the floz (fluid ounce). Despite its name it's a volume measure, not a weight measure. There are a lot of fluids out there and the volume of each it takes to weigh an ounce will vary accordingly.

Addendum to my previous post. Maybe it had something to do with it's internal volume (measured in barrels).
