40 oz = 2.5 lbs. One pound equals to 16 ounces and one ounce equals 0.06 of a pound. Also this relates only to solid (weight) ounces. There are two different kinds of ounces, ounces of weight/mass and ounces of volume (fluid). This can change when you are using the ounces to measure a non-liquid such as flour or sugar since the weight of dry items is not the same as their volume. An ounce of volume is called a "fluid ounce."
