bbq: I need 5 gallons of BBQ sauce and they sell it by lbs. How many lbs would I need?|||By the way water weighs 8.34 pounds. 16 oz BBQ sauce = 2.0 pounds 120 oz = 1 gallon. 120/16=7.5*2.0=15 pounds. 5 gallons*15 pounds= 75lbs.|||That would depend on how much a cup of BBQ sauce weighs. Edit: According to http://www.gourmetsleuth.com 1 cup of catsup = 0.53 pounds. I'm assuming catsup has the same density as BBQ sauce because BBQ is made out of catsup. 9 pounds of BBQ would be 17 cups or a little over 1 gallon. 5 gallons = 80 cups so 5 gallons = 42.4 pounds|||It would be approximately 1 gallon. BBQ sauces vary slightly in what they weigh per gallon based on the content of tomato solids. You should get about 50 lbs. But buy a good one like Sweet Baby Rays or KC Masterpiece and you may be able to use less because they are of a higher quality. |||1 gallon of water equals 8.33 lbs. 1 gallon of gasoline equals 5.8 to 6.5 lbs. BBQ sauce would be closer to water|||It's about 1 gallon. Laughing at the guy who said 16 oz of bbq sauce weighs 2 pounds...NO..it weighs 16 oz...1 pound..LOL
