About Gallon (US)
The US liquid gallon is defined as 231 cubic inches (about 3.78541 liters). US recipes, fuel economy, and retail liquids typically use US gallons.
About Fluid Ounce (UK)

How to convert gallons (us) to fluid ounces (uk)
1 gallon (us) is equal to 133.22786939985789 fluid ounce (uk):
1 gal = (3.78541178 L ÷ 0.0284130625 L) ukfloz = 133.22786939985789 ukfloz
Each gallon (us) is defined as 3.78541178 L and each fluid ounce (uk) as 0.0284130625 L, so one gal equals 3.78541178 ÷ 0.0284130625 ukfloz = 133.22786939985789 ukfloz.
Let V(gal) be the numeric value of the same volume measured in Gallon (US) (gal), and V(ukfloz) the value in Fluid Ounce (UK) (ukfloz). Then:
V(ukfloz) = V(gal) × (3.78541178 / 0.0284130625)
Equivalently, divide by how many gal fit into one ukfloz (liters per ukfloz divided by liters per gal):
V(ukfloz) = V(gal) ÷ 0.00750593704234
Or: fluid ounce (uk) = gallon (us) ÷ 0.00750593704234
Examples
Example #1: Convert 20 gal to fluid ounce (uk)
20 gal = 20 gal × (3.78541178/0.0284130625) ukfloz = 2664.557388 ukfloz
20 gal = 20 gal ÷ 0.00750593704234 = 2664.557388 ukfloz
Example #2: Convert 50 gal to fluid ounce (uk)
50 gal = 50 gal × (3.78541178/0.0284130625) ukfloz = 6661.39346999 ukfloz
50 gal = 50 gal ÷ 0.00750593704234 = 6661.39346999 ukfloz
Summary
To convert Gallon (US) to Fluid Ounce (UK), multiply the value in gal by the ratio of liters per gal divided by liters per ukfloz. Equivalently: value_ukfloz = value_gal × (3.78541178 / 0.0284130625). Numerically, 1 gal equals 133.2278693998579 ukfloz.
Relationship context
You are converting between US customary fluid / volume (Gallons (US)) and UK imperial fluid / volume (Fluid Ounces (UK)). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 1.332279e+2.
