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.
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.
How to convert fluid ounces (us) to cubic inches
1 fluid ounce (us) is equal to 1.8046875 cubic inches:
1 floz = (0.0295735295625 L ÷ 0.016387064 L) in3 = 1.8046875 in3
Each fluid ounce (us) is defined as 0.0295735295625 L and each cubic inches as 0.016387064 L, so one floz equals 0.0295735295625 ÷ 0.016387064 in3 = 1.8046875 in3.
Let V(floz) be the numeric value of the same volume measured in Fluid Ounce (US) (floz), and V(in3) the value in Cubic Inches (in3). Then:
V(in3) = V(floz) × (0.0295735295625 / 0.016387064)
Equivalently, divide by how many floz fit into one in3 (liters per in3 divided by liters per floz):
V(in3) = V(floz) ÷ 0.55411255411255
Or: cubic inches = fluid ounce (us) ÷ 0.55411255411255
Examples
Example #1: Convert 20 floz to cubic inches
20 floz = 20 floz × (0.0295735295625/0.016387064) in3 = 36.09375 in3
20 floz = 20 floz ÷ 0.55411255411255 = 36.09375 in3
Example #2: Convert 50 floz to cubic inches
50 floz = 50 floz × (0.0295735295625/0.016387064) in3 = 90.234375 in3
50 floz = 50 floz ÷ 0.55411255411255 = 90.234375 in3
Summary
To convert Fluid Ounce (US) to Cubic Inches, multiply the value in floz by the ratio of liters per floz divided by liters per in3. Equivalently: value_in3 = value_floz × (0.0295735295625 / 0.016387064). Numerically, 1 floz equals 1.8046875 in3.
Relationship context
Both units are US customary fluid / volume in this tool’s grouping. Conversions use fixed liter equivalents, so factors are consistent for cooking, engineering, and cross-checking labels. The factor from Fluid Ounce (US) to Cubic Inches is 1.804688e+0 (1 floz = 1.8046875 in3).
