Swedish units for volume in Metric? #282
Description
Hello,
I'm currently using convert().list('volume') along with a custom config to exclude imperial units from the list. However, I was surprised to see swedish units for volume mixed in with the list of metric units. While I understand they are probably based on the metric system, it seems to me they would be better suited as custom units since they are regional and not in the "International system of units" https://en.wikipedia.org/wiki/International_System_of_Units (which seems like it should be the default for metric units.
Anyhow, just seems like these should maybe be moved elsewhere so that others (and myself) wanting generally accepted metric units don't have to filter these out.
