Converting fluid ounce to us quart comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using us quart, or a laboratory protocol may specify volumes in fluid ounce that need to be measured with equipment calibrated in us quart.
In everyday use, knowing that 5 fl oz = 0.1562 qt and 10 fl oz = 0.3125 qt covers most common situations. For bulk calculations, 100 fl oz = 3.125 qt is a useful anchor. The reverse conversion — us quart back to fluid ounce — uses the factor 32, so 1 qt = 32 fl oz.
All conversions use the internationally recognized factor of exactly 1 fl oz = 0.03125 qt. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.
Formula: US Quart = Fluid Ounce × 0.031249967
Multiply any fluid ounce value by 0.031249967 to get us quart. One fluid ounce equals 0.031249967 qt.
Reverse: Fluid Ounce = US Quart × 32.000034
Fluid ounces ÷ 32 = quarts. Exact.
16 fl oz = 0.5 qt = 1 pint. 32 fl oz = 1 qt. 128 fl oz = 4 qt = 1 gal.
Quarts × 32 = fl oz.
Labels product nutrition facts and serving sizes in fluid ounces as required by FDA.

The US fluid ounce is defined as 1/128 of a US gallon, exactly 29.5735 mL. The US and UK fl oz differ: the US is 29.57 mL while the Imperial fl oz is 28.41 mL.
Fluid ounces appear on every US beverage container: a soda can is 12 fl oz, a water bottle is 16.9 fl oz, and a US shot glass is 1.5 fl oz.
Interesting fact: Despite sharing the name 'ounce', the fluid ounce measures volume, not weight. One fl oz of water weighs about 1.04 oz, but one fl oz of honey weighs about 1.5 oz.
The US liquid quart is one-quarter of a US gallon, equal to 946.353 mL. The word 'quart' comes from Old French quarte (fourth part), dating to medieval England.
Quarts are standard in American cooking and food packaging: motor oil, paint, cream, and ice cream are commonly sold in quart containers.
Interesting fact: The US quart and the Imperial quart differ significantly — the Imperial quart is 1.136 liters versus 0.946 liters for the US quart.
