Sugar has 45 points of gravity per pound. So, one pound of sugar raises the gravity in one gallon by 45 points. A half pound raises the gravity in one gallon by 22.5 points. etc, etc. By the same token, a pound of sugar will raise the gravity in five gallons by 9 points (45 points/5 gallons=9)
Maybe I sound like a high school math teacher, but it's handy to know the approximate sugar content of the ingredients you use often. Sugar 45 points/lb. Malt extract 36 points/lb. DME 45 points/lb. Honey 36 points/lb. Most fruits are about 5-10% sugar, so they add about 3 or 4 points/lb. Some of these numbers vary a little, but they will get you in the ballpark. Just multiply by the number of pounds of the ingredient and divide by the number of gallons in your batch.
