I have this strange capacity for remembering odd details, meaningless trivia, strange facts. For example, water weighs 8.33 pounds per gallon. I don't know if there's a difference in the weight of a gallon of salt water. It would be fun to know that. In school, I was the one bound to remember the weird rules about things. I could recite all the strange factual scenario details from a given hypothetical problem. So it bugs me when I can't remember the speed of light (I know it now) or who wrote a certain piece of literature. I also know what a certain scientist is famous for and what that scientist died of (but the latter part wasn't part of the test--just something I threw in as a bonus).

I need a life.
If you want the exact answer, you need to know the ratio of salt to water. According to what I researched, salt water weighs ~64 lbs/cu. ft., and fresh water comes in at about 62.2 lbs/cu. ft. There are 7.4805 gallons in a cubic foot. So a gallon of salt water weighs 8.556 lbs.

Aviation fuel weighs 6 pounds/gallon.
