About Cubic Inches
The cubic inch is the volume of a cube one inch on a side. Engine displacement in the US and small volumes in machining use cubic inches.
About Fluid Ounce (UK)
The UK fluid ounce is 1/160 of an imperial gallon (about 28.4131 ml). UK recipes and beverages may use imperial fluid ounces.
How to convert cubic inches to fluid ounces (uk)
1 cubic inches is equal to 0.57674402398545 fluid ounce (uk):
1 in3 = (0.016387064 L ÷ 0.0284130625 L) ukfloz = 0.57674402398545 ukfloz
Each cubic inches is defined as 0.016387064 L and each fluid ounce (uk) as 0.0284130625 L, so one in3 equals 0.016387064 ÷ 0.0284130625 ukfloz = 0.57674402398545 ukfloz.
Let V(in3) be the numeric value of the same volume measured in Cubic Inches (in3), and V(ukfloz) the value in Fluid Ounce (UK) (ukfloz). Then:
V(ukfloz) = V(in3) × (0.016387064 / 0.0284130625)
Equivalently, divide by how many in3 fit into one ukfloz (liters per ukfloz divided by liters per in3):
V(ukfloz) = V(in3) ÷ 1.73387145494763
Or: fluid ounce (uk) = cubic inches ÷ 1.73387145494763
Examples
Example #1: Convert 20 in3 to fluid ounce (uk)
20 in3 = 20 in3 × (0.016387064/0.0284130625) ukfloz = 11.5348804797 ukfloz
20 in3 = 20 in3 ÷ 1.73387145494763 = 11.5348804797 ukfloz
Example #2: Convert 50 in3 to fluid ounce (uk)
50 in3 = 50 in3 × (0.016387064/0.0284130625) ukfloz = 28.8372011993 ukfloz
50 in3 = 50 in3 ÷ 1.73387145494763 = 28.8372011993 ukfloz
Summary
To convert Cubic Inches to Fluid Ounce (UK), multiply the value in in3 by the ratio of liters per in3 divided by liters per ukfloz. Equivalently: value_ukfloz = value_in3 × (0.016387064 / 0.0284130625). Numerically, 1 in3 equals 0.5767440239854469 ukfloz.
Relationship context
You are converting between US customary fluid / volume (Cubic Inches) 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 5.767440e-1.
