Myself and a few other players in our campaign are trying to set up some wagons for a long haul for a campaign quest that will take us away from civilization for over a year. We are looking at the math for holding rations and materials for preserving food, and are wondering how many rations could we fit into one barrel. The PHB says on page 153 that 1 barrel can hold “40 gallons liquid, 4 cubic feet solid”.

One player says that there can only be 10 rations per barrel because they weigh 2 lbs., but another says that the 2 lbs. was a typo and they are 1 lbs. for a day's rations.

This has became an issue that has caused a fight and players getting angry at each other.

So in the end: how much do rations weigh and how many can fit in a barrel?
