Convert cubic inches to cubic centimeters for engine displacement, machining, and manufacturing. Accurate calculator with 1 in³ = 16.387064 cm³ conversion factor.
1 cubic inch equals 16.387075841025702 cubic centimeter
Formula: cm³ = in³ × 16.3871
The conversion between cubic inches and cubic centimeters is essential for engineers and mechanics worldwide. With 1 cubic inch equaling precisely 16.387064 cubic centimeters, understanding this relationship is critical for engine specifications, manufacturing tolerances, and international technical documentation. This conversion bridges the Imperial system used primarily in North America with the metric system adopted globally.
Engine displacement specifications directly affect performance ratings, fuel consumption calculations, and regulatory compliance. A 5.0-liter engine (305 cubic inches) misidentified as 300 cubic inches creates a 1.6% error affecting horsepower estimates, emissions testing, and parts compatibility. Precision in this conversion impacts warranty claims, performance tuning, and international vehicle documentation.
Engine displacement is the primary specification determining vehicle classification, emissions standards, and performance characteristics. Manufacturers convert between cubic inches and cubic centimeters (liters) for engine blocks, cylinder volumes, and combustion chamber specifications. International compliance requires accurate conversion for EPA regulations, EU standards, and warranty documentation across markets.
Machining operations require exact volume calculations for material removal rates, tool path planning, and component tolerances. CNC machines programmed in metric systems must convert Imperial design specifications. Cutting fluid volumes, chip evacuation calculations, and bore/stroke measurements depend on accurate conversion between cubic inches and cubic centimeters.

This cubic inch to cubic centimeter converter uses high-precision conversion factors to ensure accurate results for professional and academic use.
Our calculator provides results with up to 10 decimal places for maximum accuracy.
Exactly 16.387064 cubic centimeters equal 1 cubic inch. This precise relationship comes from the internationally defined inch measurement (2.54 centimeters exactly). For practical engineering: multiply cubic inches by 16.387064 for exact metric conversion. Quick mental math: multiply by approximately 16.4 for estimates, but always use the full factor for specifications and compliance documentation.
The United States primarily adopted Imperial measurements and maintained cubic inches as the standard for automotive specifications. Europe standardized on the metric system and uses cubic centimeters/liters. This historical difference persists because manufacturers optimize documentation for their primary markets. Modern vehicles increasingly display both measurements for international recognition. A 5.0-liter engine (305 cubic inches) is the same regardless of labeling - the conversion factor ensures technical accuracy across markets.
