📖 About Gallons to Pints

Liquid Kitchen & Brewery Metrology Standards

In the US Customary liquid framework, 1 gallon holds exactly 8 pints ($128\text{ fluid ounces}$ or $4\text{ quarts}$).

Primary Liquid Volume Equivalents

  • 1 Gallon: $\equiv 8\text{ Pints} = 4\text{ Quarts} = 16\text{ Cups} = 128\text{ fl oz} = 3,785.41\text{ mL}$
  • 0.5 Gallon: $= 4\text{ Pints} = 2\text{ Quarts} = 8\text{ Cups} = 64\text{ fl oz}$
  • 1 Quart: $= 2\text{ Pints} = 4\text{ Cups} = 32\text{ fl oz} = 946.35\text{ mL}$
  • 1 Pint: $= \frac{1}{8}\text{ Gallon} = 0.125\text{ Gallon} = 2\text{ Cups} = 16\text{ fl oz} = 473.18\text{ mL}$

Equations

  • $\text{Pints} = \text{Gallons} \times 8$
  • $\text{Gallons} = \frac{\text{Pints}}{8}$
