The table below provides density figures for many common (and some not-so-common) substances. This information is useful for determining the weight (or volume) of objects and cargo. This table was pieced together from a wide variety of sources, listed in full at the bottom of the page. The inspiration for this comes from the old Dragon magazine article, "How Heavy is My Giant".
These figures have not been rigorously checked. Do not rely on this as a scientific reference!
Note on measures: Specific gravity is a measure of an object's density. A cubic centimeter of water at 4°C weighs 1 gram, and has a specific gravity of 1. The specific gravity numbers below can be read as "grams per cubic centimeter" (or kg/liter). A solid object with a specific gravity greater than 1 will sink in water. Weight in pounds per cubic inch and foot is also provided to save non-metric users some time on the calculator.
I may not have been posting on the blog but I haven’t been idle. I’ve just posted a revised map and version 1 of the new "Mythosa Cyclopedia". I’d like to say I’ve tweaked things slightly, but that would be a little inaccurate. But in my defense, that wasn’t my original intention! Below is a long rambling about how this new version came to be.
Though I’ve changed Mythosa quite a bit over the years (that’s actually part of the world lore now; the cycle of destruction and rebirth is a central part of a universal "monomyth"), the last incarnation was intended to be the last one. I was happy with the world, but my map looked too amateurish. So I started to look online for someone to hire to make a professional-looking map of Mythosa.
In the process I found an application called "Wonderdraft". I’d never heard of it before, but once I bought it and started using it, I was amazed. This was the mapping program I’d wanted for years, it just didn’t exist until now…
(This is related to this post from a few years ago). Before I wrote the latest version of the Mythosa PDF (well, version 1.0 at least), I was trying to determine a new format that was both useful and practical. Generally, campaign books follow a fairly standard design that we’re all pretty familiar with by now: some sort of summary introduction (sometimes with a bit of fiction that is usually terrible), then an extensive chapter on the world’s history that will mostly be ignored, a chapter that goes into way more detail than necessary on the political entities of the world, another one fleshing out the religions, and then others that vary but cover things like why these elves are different, and what the various organizations and factions are, possibly a bunch of new mechanical elements (for games like D&D or Pathfinder this would include new monsters, new magic items, new spells, new feats, etc.). Now, let me make it clear that I’m a fan of campaign setttings; I love reading up on n…
