One more bit of background that may help you make sense of this. In DF, material properties, among other things, are defined in the "raws" (text files that contain assorted figures, like solid density). You can see an example of what they look like here, on the DF wiki - http://dwarffortresswiki.org/index.php/v0.34:Saguaro/raw http://dwarffortresswiki.org/index.php/v0.34:Saguaro/raw --- Density was determined experimentally. Contact Uristocrat for a sample if you want to verify this yourself. A 6g (+/- 0.1g) piece of dry Saguaro wood had a volume of approximately 14 cm^3 (+/- 1 cm^3) [SOLID_DENSITY:430]
