This article is about the current version of DF.
Note that some content may still need to be updated.

Weight, or sometimes more correctly termed mass, is an item property, and is measured in the unit Γ, also sometimes known as urists, or more commonly as the kilogram, its equivalent real-life unit.

Weight is largely used by the game to determine how fast someone or something should move, due to encumbrance effects and carry weight restrictions; to calculate damage, since object mass factors into impact momentum; and to some extent to make temperature calculations, as mass factors into heat capacity. Note that, for DF, weight and mass are currently indistinguishable because, as it stands, DF gravity is uniform both across the whole universe and from world to world and buoyancy isn't implemented.

Weight is displayed as a quantity associated with an item. Weight calculation is not entirely straightforward, since each item category — or sometimes even individual items — have their own formula for determining weight.

Weight Calculation

The general form for calculating weight in DF is to take the material density (as found in the raws) multiplied by the item's volume.

Weight (in Γ) = Density (in kg/m3) * Volume (in cm3) / 1,000,000 (cm3/m3)

Internally, all custom volume/capacity numbers are rounded down to the nearest multiple of 10 - thus, if you define a tool with [SIZE:15], it will actually behave as if you had specified [SIZE:10].

An item's volume is also used to determine workshop clutter as well as how many items can fit into a container.

Assorted item weights

Weight displayed in-game is rounded down to a whole number.

Item Weight in Γ(kg) Notes
Iron anvil 78.500 Same as a steel anvil.
Aluminum bar 16.200 Least dense normal metal.
Steel bar 47.100 Same as an iron or pig iron bar.
Platinum bar 128.400 Most dense metal.
Feather (wood) barrel 2.000 Least dense wood, found only in good biomes.
Willow barrel 7.800 Least dense common wood, found near water in many biomes.
Tunnel tube barrel 10.000 Least dense cavern wood, found only in lower caverns.
Tower cap barrel 12.000 Same as a barrel of acacia, ash, fungiwood, goblin-cap, mahogany, pear, or spore wood.
