About Cubic Inch (in³)
Definition
The cubic inch is an imperial unit of volume equal to the space occupied by a cube one inch on each side.
Mathematical Relationship
1 in³ = 16.387064 mL = 16.387064 cm³. There are 1,728 in³ in one cubic foot.
Conversion Formula
To mL: multiply by 16.387064. To liters: multiply by 0.016387064. To cubic centimeters: multiply by 16.387064.
Practical Applications
Engine displacement (classic American V8s measured in cubic inches), small container volumes, and manufacturing specifications.
Interesting Facts
The iconic Chevrolet 'small block 350' engine has a displacement of 350 cubic inches (5.7 liters). A golf ball is about 2.48 in³.
Common Mistakes
Confusing cubic inches with fluid ounces — 1 in³ ≈ 0.554 fl oz (US). They are not equivalent.
Educational Tips
Think of a standard die (game dice) — it's roughly 1 in³. A cubic inch of water weighs about 0.578 ounces.
About Gallon (UK) (gal (UK))
Definition
The UK (imperial) gallon is a unit of volume equal to 160 UK fluid ounces, or exactly 4.54609 liters.
Mathematical Relationship
1 UK gal = 4 UK qt = 8 UK pt = 160 UK fl oz = 4.54609 L ≈ 1.201 US gal.
Conversion Formula
To liters: multiply by 4.54609. To US gallons: multiply by 1.20095. To cubic meters: multiply by 0.00454609.
Practical Applications
UK road signs (mpg), older fuel consumption references, and some Caribbean and Middle Eastern markets that still use imperial units.
Interesting Facts
A UK gallon is about 20% larger than a US gallon. A car rated at 40 mpg (UK) gets only about 33 mpg (US).
Common Mistakes
Misinterpreting UK mpg as US mpg — UK figures look higher because the imperial gallon is larger.
Educational Tips
UK gallon ≈ 4.55 L ≈ 1.2 US gallons. The UK gallon was defined so that 1 gallon of water = 10 pounds.
