Fluid ounces and Quarts
Everything you need to know about converting quarts to fluid ounces.
Quarts and Fluid Ounces Explained
A quart (qt) equals 32 fluid ounces, 4 cups, or 946.353 milliliters. You see quarts on milk cartons, broth containers, and ice cream packaging. A quart is one-quarter of a gallon.
A fluid ounce (fl oz) equals about 29.574 milliliters. It's the most common unit on US beverage labels — water bottles (16.9 fl oz), soda cans (12 fl oz), and energy drinks (8.4 fl oz) all use fluid ounces. Note that a fluid ounce measures volume, not weight.
Common Uses for This Conversion
Water intake tracking is a top use case. Health guidelines recommend about 64 fl oz (2 quarts) of water daily. Knowing 1 quart = 32 fl oz helps you track how many bottles or glasses you need.
Cocktail and beverage recipes frequently mix quarts and fluid ounces. A punch recipe might call for 2 quarts of juice, but individual servings are in fluid ounces. 2 quarts = 64 fl oz, enough for about 8 eight-ounce servings.
