You should be able to remember this;

You should be able to remember by the kingdom of G. Draw a big G (for gallons) inside draw four Q( for quarts) inside of the Q draw two P(for pints) and inside of that draw 2 C (for cups) and inside of the C draw 8 O(for ounces). The story goes something like this, there once was a kingdom G that had 4 queens. Each queen had two princesses. Each princess had two cats. Each cat had 8 Orange balls. The end.
