How much water does a waterskin hold?

[A2Z]

This information is conspicuously absent from the PHB. Normally I don't suppose it would matter that much but at the moment I'm running a Dark Sun game and it's suddenly become more important.

So far I've worked out that one waterskin will hold about a quart of liquid. This seems to work with the 4lbs weight given in the PHB but I'm interested in what others think.

1 days worth.

It would be 2 quarts. As water is about 8 pounds to a gallon.

Yep, and that approximately matches real waterskins.

In 2E Dark Sun it was assumed that waterskins held 1 gallon, which is a day's worth if your character is active during the daytime, and is probably the most convenient size in a Dark Sun campaign.

Yeah, I don't think the PHB has a lot of measurements. Like how big a backpack or sack is (how much can they hold)? How much weight can they support? Stuff like that...

Yes, 3.0 slacked in the detail department for those things. The 4lb weight in the PHB would imply a 1/2 gallon. Changing to 1 gallon and keeping track of "days of water" would probably make the bookkeeping much easier.
