You should use the chart and keep it somewhere safe so you can always see it in case you need it, but I will give you this answer for now...
There's a big G (gallons), then in that G there are 4 q's (quarts), in each of those q's there's 2 p's (pints), and in each of the p's there's 2 c's (cups).
I'll leave a link in the comments to that chart if you want to copy it down or print it out.
