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 (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 cubic inches to fluid ounces (us)
1 cubic inches is equal to 0.55411255411255 fluid ounce (us):
1 in3 = (0.016387064 L ÷ 0.0295735295625 L) floz = 0.55411255411255 floz
Each cubic inches is defined as 0.016387064 L and each fluid ounce (us) as 0.0295735295625 L, so one in3 equals 0.016387064 ÷ 0.0295735295625 floz = 0.55411255411255 floz.
Let V(in3) be the numeric value of the same volume measured in Cubic Inches (in3), and V(floz) the value in Fluid Ounce (US) (floz). Then:
V(floz) = V(in3) × (0.016387064 / 0.0295735295625)
Equivalently, divide by how many in3 fit into one floz (liters per floz divided by liters per in3):
V(floz) = V(in3) ÷ 1.8046875
Or: fluid ounce (us) = cubic inches ÷ 1.8046875
Examples
Example #1: Convert 20 in3 to fluid ounce (us)
20 in3 = 20 in3 × (0.016387064/0.0295735295625) floz = 11.0822510823 floz
20 in3 = 20 in3 ÷ 1.8046875 = 11.0822510823 floz
Example #2: Convert 50 in3 to fluid ounce (us)
50 in3 = 50 in3 × (0.016387064/0.0295735295625) floz = 27.7056277056 floz
50 in3 = 50 in3 ÷ 1.8046875 = 27.7056277056 floz
Summary
To convert Cubic Inches to Fluid Ounce (US), multiply the value in in3 by the ratio of liters per in3 divided by liters per floz. Equivalently: value_floz = value_in3 × (0.016387064 / 0.0295735295625). Numerically, 1 in3 equals 0.5541125541125541 floz.
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 Cubic Inches to Fluid Ounce (US) is 5.541126e-1 (1 in3 = 0.5541125541125541 floz).
