People love to express their gratitude for a favorite tool or gadget by claiming that it's worth its weight in gold, a reference which is lost on most of us who don't know how much a pound of gold is actually worth. Thankfully Evil Mad Scientist Laboratories has cooked up a handy reference guide to help you measure the monetary density of things. This graphical comparison covers the weight value of U.S. currency, human blood, commodities, illicit drugs and pretty much everything else in between.

I'm still trying to take all this information in and it cracks me up how much a pound of many of these items are worth. Still, I noticed that a few items are noticeably absent from this lineup so I took the liberty of translating these into units to further expand your weight to value ratios.

• Gasoline - $1.79 / lb locally, a gallon of gas weighs 6.15 pounds.
  
• Crude oil - 39 cents / lb as of today, a gallon of crude is ~7 lbs, a barrel of oil contains 42 gallons at $118.35
  
• Quarter Pounder with cheese - $18 / lb, assuming 1/4 lb weight of burger and bun post cooking.
• With gold trading around $830 per ounce, and 16 ounces in a pound, a pound of gold is worth $13,280.

With energy prices coming across that low in pounds I wouldn't be too shocked to see pumps switching over to per pound pricing in the near future! In a more practical sense, I'm sure list will prove to be worth its weight in quarters when you turn a quick profit this weekend, betting some poor chump that a pound of peacock feathers is worth more than a pound of Uranium!
