m (scale volumes up by 10 so the weight formula makes sense, as I did earlier on the 0.34/later pages)

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 * Volume / 100,000

:Weight (in Γ) = Density (in kg/m<sup>3</sup>) * Volume (in cm<sup>3</sup>) / 1,000,000 (cm<sup>3</sup>/m<sup>3</sup>)

Internally, all custom volume/capacity numbers are rounded down to the nearest multiple of 10 - thus, if you define a weapon with [SIZE:15], it will actually behave as if you had specified [SIZE:10].
  
 
Items also have a "bulk" which does not depend on the material and is used to determine [[clutter]] as well as how many items can fit into a container.

This article is about an older version of DF.

Weight is an item property, and is measured in units Γ, also known as urists - one unit urist is equivalent to one real kilogram.

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[edit]

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 weapon with [SIZE:15], it will actually behave as if you had specified [SIZE:10].

Items also have a "bulk" which does not depend on the material and is used to determine clutter as well as how many items can fit into a container.
