How to convert fluid ounces (us) to fluid ounces (uk)
1 fluid ounce (us) is equal to 1.04084273078624 fluid ounce (uk):
1 floz = (0.0295735295625 L ÷ 0.0284130625 L) ukfloz = 1.04084273078624 ukfloz
Each fluid ounce (us) is defined as 0.0295735295625 L and each fluid ounce (uk) as 0.0284130625 L, so one floz equals 0.0295735295625 ÷ 0.0284130625 ukfloz = 1.04084273078624 ukfloz.
Let V(floz) be the numeric value of the same volume measured in Fluid Ounce (US) (floz), and V(ukfloz) the value in Fluid Ounce (UK) (ukfloz). Then:
V(ukfloz) = V(floz) × (0.0295735295625 / 0.0284130625)
Equivalently, divide by how many floz fit into one ukfloz (liters per ukfloz divided by liters per floz):
V(ukfloz) = V(floz) ÷ 0.96075994040388
Or: fluid ounce (uk) = fluid ounce (us) ÷ 0.96075994040388
Examples
Example #1: Convert 20 floz to fluid ounce (uk)
20 floz = 20 floz × (0.0295735295625/0.0284130625) ukfloz = 20.8168546157 ukfloz
20 floz = 20 floz ÷ 0.96075994040388 = 20.8168546157 ukfloz
Example #2: Convert 50 floz to fluid ounce (uk)
50 floz = 50 floz × (0.0295735295625/0.0284130625) ukfloz = 52.0421365393 ukfloz
50 floz = 50 floz ÷ 0.96075994040388 = 52.0421365393 ukfloz
Summary
To convert Fluid Ounce (US) to Fluid Ounce (UK), multiply the value in floz by the ratio of liters per floz divided by liters per ukfloz. Equivalently: value_ukfloz = value_floz × (0.0295735295625 / 0.0284130625). Numerically, 1 floz equals 1.040842730786236 ukfloz.
Relationship context
You are converting between US customary fluid / volume (Fluid Ounces (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 1.040843e+0.
