About Quart (UK)
The UK imperial quart is one quarter of an imperial gallon (about 1.1365 liters). It appears in UK cooking and beverage measures.
About Fluid Ounce (US)
The US fluid ounce is 1/128 of a US gallon (about 29.5735 ml). US nutrition labels and recipes use fluid ounces for liquids.
How to convert quarts (uk) to fluid ounces (us)
1 quart (uk) is equal to 38.43039761615536 fluid ounce (us):
1 ukqt = (1.1365225 L ÷ 0.0295735295625 L) floz = 38.43039761615536 floz
Each quart (uk) is defined as 1.1365225 L and each fluid ounce (us) as 0.0295735295625 L, so one ukqt equals 1.1365225 ÷ 0.0295735295625 floz = 38.43039761615536 floz.
Let V(ukqt) be the numeric value of the same volume measured in Quart (UK) (ukqt), and V(floz) the value in Fluid Ounce (US) (floz). Then:
V(floz) = V(ukqt) × (1.1365225 / 0.0295735295625)
Equivalently, divide by how many ukqt fit into one floz (liters per floz divided by liters per ukqt):
V(floz) = V(ukqt) ÷ 0.02602106826966
Or: fluid ounce (us) = quart (uk) ÷ 0.02602106826966
Examples
Example #1: Convert 20 ukqt to fluid ounce (us)
20 ukqt = 20 ukqt × (1.1365225/0.0295735295625) floz = 768.607952323 floz
20 ukqt = 20 ukqt ÷ 0.02602106826966 = 768.607952323 floz
Example #2: Convert 50 ukqt to fluid ounce (us)
50 ukqt = 50 ukqt × (1.1365225/0.0295735295625) floz = 1921.51988081 floz
50 ukqt = 50 ukqt ÷ 0.02602106826966 = 1921.51988081 floz
Summary
To convert Quart (UK) to Fluid Ounce (US), multiply the value in ukqt by the ratio of liters per ukqt divided by liters per floz. Equivalently: value_floz = value_ukqt × (1.1365225 / 0.0295735295625). Numerically, 1 ukqt equals 38.43039761615536 floz.
Relationship context
You are converting between UK imperial fluid / volume (Quarts (UK)) and US customary fluid / volume (Fluid Ounces (US)). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 3.843040e+1.
