v50.15 · v0.47.05 This article is about the current version of DF.Note that some content may still need to be updated. |
| Material properties |
| Defined: Value • Color • Density • Strain at yield • Temperature values |
| Derived: Magma safety • Fire safety |
| Fluids: Depth • Flow • Pressure |
Density is a material property that, along with the volume of the object, affects the weight 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
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.
