Oh dear LORD, I had no idea "rock superstar" Glenn Danzig had become a unit of measurement.
Well, now that we know this, I'm sure you're wondering exactly HOW BIG IS YOUR APARTMENT IN DANZIGS?! DUH!! I certainly did!! It's easy to find out by simply plugging in the number of (ahem) square meters (!!) into the little field HERE...and SHAZAM!!
If you want, you can convert any number of meters, kilograms, joules (!!), or liters into Danzigs, as well. I've been converting all day; it's been fantastic, I've learned a lot about stuff.
