There are two pints to a quart, and four quarts to a gallon. Or, two quarts (four pints) to half a gallon. So three half gallons would be 3 x 4 pints = 12 pints. 12 pints is also 6 quarts. Did you know there are only two countries in the world that still use the old Imperial system, all the rest use metric units.
