* Liquids happen to be 1kg to 1L (weight to volume), and because of this, are often referenced in liters (L). Many sold items have different kg to L relationships. Examples:
** A small bucket can hold 12 L. A full bucket of water containers 12 L of water weighting 12 kg.
** A pottery bowl can hold 9 L and weights 0.50 kg. A filet fillet of fish is 0.20 L and weights 0.30 kg. Thus, a pottery bowl can hold 45 filets fillets (9 / 0.2 = 45) and will weight 14 kg (13.50 kg filetfillet, 0.50 kg bowl).
* Volume puts limits on how much can fit in a container. All containers themselves consume slightly more volume then they hold. Hypothetically players can carry infinite volume and containers can hold infinite weight.
