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 Fluid Ounce (UK) (fl oz (UK))
Definition
The UK fluid ounce is a unit of liquid volume equal to 1/160 of an imperial gallon, or approximately 28.413 milliliters.
Mathematical Relationship
1 UK fl oz = 1/20 UK pt = 1/160 UK gal ≈ 28.4131 mL. It is about 4% smaller than a US fluid ounce.
Conversion Formula
To mL: multiply by 28.4131. To US fl oz: multiply by 0.96076. To UK pints: divide by 20.
Practical Applications
Older UK recipes, some beverage labels in Commonwealth countries, and traditional pharmaceutical dosing.
Interesting Facts
Paradoxically, the UK fluid ounce is smaller than the US fluid ounce (28.41 vs. 29.57 mL), even though UK pints and gallons are larger.
Common Mistakes
Assuming UK and US fluid ounces are the same — they differ by about 4%. This seems small but accumulates in recipes.
Educational Tips
UK fl oz ≈ 28.4 mL, US fl oz ≈ 29.6 mL. The UK has more fl oz per pint (20) vs. US (16), but each UK fl oz is smaller.
