My players have taken a side quest to deliver a chest full of vials of basic poison, and I want a ballpark estimate of how many doses of poison there are in the chest.
Poison, basic (vial); weight: -
Chest; Container Capacity: 12 cubic feet/300 pounds gear
Vial; Container Capacity: 4 ounces liquid
This would be trivial to estimate if the poison had a weight listed, but since it has no listed weight I want to use the listed volumes.
Four fluid ounces is 0.00417752 cubic feet, and 12 cubic feet / 0.00417752 cubic feet per vial = 2,872.5 vials
That's an upper bound since it's not taking into account the space that the glass of the vial would take up, and it assumes perfect packing without empty space. What would a more reasonable estimate be? 1,436, assuming we lose half of the upper bound due to bottle and suboptimal packing? 2,000, just to round down to the nearest thousand? 2,500, to round down to the nearest 500?
I understand that this is getting too specific for the game, since this isn't a reality simulator, but I just want the numbers to be reasonable. I had initially thought "about 100 vials", but that feels incredibly low, looking at all of the space in the chest. Even if we needed room for ensuring vials didn't break in transit, I feel like my initial estimate is still wrong by an order of magnitude.
