Matt,

According to Wikipedia: "Avgas has a density of 6.02 lb/US gallon at 15 °C".
Not sure how 'correct' this is.

I've seen several different values, but most are less than 6.00 lbs/gal.

According to this site, the specific gravity of ConocoPhillips 100LL is 0.7.

According to this site, the density of water at 15.5C is 8.33727 lbs/gal.

Multiplying that by 0.7 yields: 5.836 lb/gal for the 100LL.

I can't vouch for the calculator site, but I trust the ConocoPhillips
MSDS much more than anything on Wikipedia, which is about the least
reliable source on the internet in my experience.
