Converting cubic inch to us cup comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using us cup, or a laboratory protocol may specify volumes in cubic inch that need to be measured with equipment calibrated in us cup.
In everyday use, knowing that 5 in³ = 0.3463 cup and 10 in³ = 0.6926 cup covers most common situations. For bulk calculations, 100 in³ = 6.926 cup is a useful anchor. The reverse conversion — us cup back to cubic inch — uses the factor 14.44, so 1 cup = 14.44 in³.
All conversions use the internationally recognized factor of exactly 1 in³ = 0.06926 cup. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.
Formula: US Cup = Cubic Inch × 0.069264291
Multiply any cubic inch value by 0.069264291 to get us cup. One cubic inch equals 0.069264291 cup.
Reverse: Cubic Inch = US Cup × 14.437454
1 in³ = 0.069264291 cup. Memorize this for instant mental estimates.
Use 0.0693 as a quick mental factor. Multiply your cubic inches value by this to estimate US cups.
To verify: multiply your result by 14.437454 to recover the original in³ value.
Compares engine displacements in cubic inches — a Harley Sportster 1200 displaces 73.2 in³.
Calculates material volume for machined parts in cubic inches for cost estimation.
Compares refrigerator and oven interior volumes in cubic inches on US spec sheets.
Determines hydraulic cylinder displacement in cubic inches for legacy US equipment.
Compares compressor capacities in cubic inch displacement for older American systems.
Calculates product and box volumes in cubic inches to optimize pallet stacking.
The cubic inch is the volume of a cube with one-inch sides, equal to exactly 16.387064 mL. It belongs to US customary and British Imperial systems, in practical use since the 17th century.
Cubic inches appear most often in engine displacement for small engines and in precision machining for material volume calculations.
Interesting fact: A standard 12-fluid-ounce US soda can has a volume of about 21.7 cubic inches.
The US customary cup is defined as exactly 8 US fluid ounces, or 236.588 mL. It was standardized by Fannie Farmer in her 1896 cookbook The Boston Cooking-School Cook Book.
The cup is the backbone of US baking: nearly every American recipe uses cup measurements for flour, sugar, butter, and liquids. Standard sets include 1 cup, ½ cup, ⅓ cup, and ¼ cup.
Interesting fact: Australia uses a metric cup of 250 mL, slightly larger than the US cup, which can cause recipe confusion in international cooking.
