1 US gallon equals exactly 128 fluid ounces. This is divided into 4 quarts or 8 pints.
How many cups are in a pint?
1 pint equals exactly 2 cups. A cup contains 8 fluid ounces, so a pint contains 16 fluid ounces.
What is a fluid dram?
A fluid dram is a small unit of liquid volume equal to 1/8 of a fluid ounce, or approximately 3.7 milliliters. It’s primarily used in pharmacy and older medical texts.
How many quarts are in a gallon?
1 gallon equals exactly 4 quarts. This is one of the most fundamental conversions in the US customary system.
