What Is a Fluid Ounce?
A fluid ounce is a unit of volume equal to 0.0295735 liters (L), the base unit for volume. 1/128 of a US gallon (29.5735 mL). [1]
The fluid ounce is classified as a US customary unit of volume. Fluid Ounces can be abbreviated as fl oz; for example, 1 fluid ounce can be written as 1 fl oz.
When working with fluid ounces (fl oz) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, fluid ounces (fl oz) are widely used across standard volume applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Quart?
A quart is a unit of volume equal to 0.9463529 liters (L), the base unit for volume. Equal to 1/4 US gallon or 2 US pints (946.35 mL). [2]
The quart is classified as a US customary unit of volume. Quarts can be abbreviated as qt; for example, 1 quart can be written as 1 qt.
When working with quarts (qt) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, quarts (qt) are widely used across standard volume applications within US customary workflows, engineering documentation, and technical data sheets.
When converting volume between fluid ounces (fl oz) and quarts (qt), keep full floating-point precision (1 fl oz = 0.03125 qt; 1 qt = 32 fl oz) during intermediate calculations and round only the final quart figure to match your instrument tolerance.
