About Gallon (UK)
The UK imperial gallon is defined as approximately 4.54609 liters. It is larger than the US liquid gallon and is used for fuel and drinks labeling in the UK.
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 gallons (uk) to cubic inches
1 gallon (uk) is equal to 277.41943279162149 cubic inches:
1 ukgal = (4.54609 L ÷ 0.016387064 L) in3 = 277.41943279162149 in3
Each gallon (uk) is defined as 4.54609 L and each cubic inches as 0.016387064 L, so one ukgal equals 4.54609 ÷ 0.016387064 in3 = 277.41943279162149 in3.
Let V(ukgal) be the numeric value of the same volume measured in Gallon (UK) (ukgal), and V(in3) the value in Cubic Inches (in3). Then:
V(in3) = V(ukgal) × (4.54609 / 0.016387064)
Equivalently, divide by how many ukgal fit into one in3 (liters per in3 divided by liters per ukgal):
V(in3) = V(ukgal) ÷ 0.00360465014991
Or: cubic inches = gallon (uk) ÷ 0.00360465014991
Examples
Example #1: Convert 20 ukgal to cubic inches
20 ukgal = 20 ukgal × (4.54609/0.016387064) in3 = 5548.38865583 in3
20 ukgal = 20 ukgal ÷ 0.00360465014991 = 5548.38865583 in3
Example #2: Convert 50 ukgal to cubic inches
50 ukgal = 50 ukgal × (4.54609/0.016387064) in3 = 13870.9716396 in3
50 ukgal = 50 ukgal ÷ 0.00360465014991 = 13870.9716396 in3
Summary
To convert Gallon (UK) to Cubic Inches, multiply the value in ukgal by the ratio of liters per ukgal divided by liters per in3. Equivalently: value_in3 = value_ukgal × (4.54609 / 0.016387064). Numerically, 1 ukgal equals 277.4194327916215 in3.
Relationship context
You are converting between UK imperial fluid / volume (Gallons (UK)) and US customary fluid / volume (Cubic Inches). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 2.774194e+2.
