About Gallon (UK)
The UK imperial gallon is defined as approximately 4.54609 liters. It is larger than the US liquid gallon and is used for fuel and drinks labeling in the UK.
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 gallons (uk) to fluid ounces (us)
1 gallon (uk) is equal to 153.72159046462144 fluid ounce (us):
1 ukgal = (4.54609 L ÷ 0.0295735295625 L) floz = 153.72159046462144 floz
Each gallon (uk) is defined as 4.54609 L and each fluid ounce (us) as 0.0295735295625 L, so one ukgal equals 4.54609 ÷ 0.0295735295625 floz = 153.72159046462144 floz.
Let V(ukgal) be the numeric value of the same volume measured in Gallon (UK) (ukgal), and V(floz) the value in Fluid Ounce (US) (floz). Then:
V(floz) = V(ukgal) × (4.54609 / 0.0295735295625)
Equivalently, divide by how many ukgal fit into one floz (liters per floz divided by liters per ukgal):
V(floz) = V(ukgal) ÷ 0.00650526706741
Or: fluid ounce (us) = gallon (uk) ÷ 0.00650526706741
Examples
Example #1: Convert 20 ukgal to fluid ounce (us)
20 ukgal = 20 ukgal × (4.54609/0.0295735295625) floz = 3074.43180929 floz
20 ukgal = 20 ukgal ÷ 0.00650526706741 = 3074.43180929 floz
Example #2: Convert 50 ukgal to fluid ounce (us)
50 ukgal = 50 ukgal × (4.54609/0.0295735295625) floz = 7686.07952323 floz
50 ukgal = 50 ukgal ÷ 0.00650526706741 = 7686.07952323 floz
Summary
To convert Gallon (UK) to Fluid Ounce (US), multiply the value in ukgal by the ratio of liters per ukgal divided by liters per floz. Equivalently: value_floz = value_ukgal × (4.54609 / 0.0295735295625). Numerically, 1 ukgal equals 153.72159046462144 floz.
Relationship context
You are converting between UK imperial fluid / volume (Gallons (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 1.537216e+2.
