1 gallon = 4 quarts
1 quart = 2 pints
1 pint = 2 cups
1 cup = 8 fluid ounces
To convert from a larger unit to a smaller unit within the US customary system, one should multiply by the conversion factor. For instance, to find out how many cups are in one gallon:
1 gallon × 4 quarts/gallon × 2 pints/quart × 2 cups/pint = 16 cups
Common US Volume Abbreviations
When referencing volume units in the US customary system, certain abbreviations are commonly accepted:
Gallon: gal
Quart: qt
Pint: pt
Cup: c
These abbreviations facilitate communication and documentation of volume measurements, such as in recipes or on product labels. It is important to distinguish these from the metric system, which uses liters and milliliters. The US customary system specifically denotes the US gallon, which is divided into the US liquid gallon and the US dry gallon—with the liquid gallon being equivalent to 3.785 liters and the dry gallon equaling approximately 4.405 liters.
Imperial System
In the Imperial system, which is used predominantly in the United Kingdom, the volume of liquid substances is typically measured in imperial gallons and cups. These units follow the traditional British measures, which differ from the US customary system.
Imperial Volume Unit Conversion
The conversion of liquid volume in the Imperial system is grounded in the relationship between imperial gallons and imperial cups. One imperial gallon is equivalent to exactly 16 imperial cups. As such, for anyone looking to convert imperial gallons to cups, they can do so by multiplying the number of gallons by 16.
