Density is a material property that, along with the volume of the object, affects the weight/mass of an object made from the material.
Density influences weight, and tests show that weight affects how much damage blunt-force weapons do. Additionally, lightweight edged weapons or attacking parts made of certain materials seem to have difficulty piercing tissue layers. Apparently, density in Dwarf Fortress is in kg/m3*. Density also affects fall damage. DF simulates falling by shooting the ground at you, so denser floors do more damage.
- (* For example, in the real world, the density of pure gold is 19.32 grams/cm3, which works out to be 19,320 kg/m3, the same numeric value as the density of DF Gold (see table below).)
Density of some materials[edit]
Note that not all forms of items are the same size, and so are not comparable when considering actual weight for practical applications, such as a door prize. A stone (including raw ore) has a size of 10,000 cm3 and a log of wood 5,000 cm3, while a bar of metal (or a block of stone or wood) have a size of only 600 cm3, a difference of ~16.67:1 for stone vs. metals, or ~8.33:1 for wood vs. metals.
