Regarding my last post of this date, you can use ratio and proportion to solve many of these type problems. For example, to find out how many liters in a gallon, get a can of diet soda or bottled water and use the data on the can or bottle to determine how many liters in a gallon. For example, a can of diet soda is 12 ounces and 355 ml. You need to know one fact such as 128 ounces in a gallon. 12/128 = 355/x. Solve this problem and you get; x=3787 or 3.787 liters. The dictionary lists the actual answer as 3.785. For water, one gram of water is = to one ml.
