Conversion Formula
The formula to convert cubic inches (ci) to cubic centimeters (cc) uses the fact one inch equals 2.54 centimeters. Since volume units cube length measurements, the conversion factor is (2.54)³.
Mathematically:
1 ci = (2.54 cm) × (2.54 cm) × (2.54 cm) = 2.54³ cm³ = 16.3871 cc
So, to convert any value from ci to cc, multiply it by 16.3871. This works because cubic centimeters measure volume in a metric system, while cubic inches use the imperial system.
Conversion Example
- Convert 5 ci to cc:
- Multiply 5 by 16.3871
- 5 × 16.3871 = 81.9355 cc
- Result: 5 ci equals 81.9355 cc
- Convert 3.2 ci to cc:
- 3.2 × 16.3871 = 52.4387 cc
- So 3.2 ci is 52.4387 cc
- Convert 12 ci to cc:
- 12 × 16.3871 = 196.6452 cc
- Therefore, 12 ci equals 196.6452 cc

Conversion Definitions
ci: Cubic inch (ci) is a unit for volume in the imperial measurement system. It represents the volume of a cube with each side measuring exactly one inch. It’s used in engineering, automotive, and manufacturing fields when measuring small volumes.
cc: Cubic centimeter (cc) is a metric volume unit equal to the volume of a cube with sides 1 cm long. It’s common in medical dosages, engine sizes, and scientific measurements, representing a precise small volume within the metric system.
Conversion FAQs
Why is the conversion factor between ci and cc 16.3871?
The factor 16.3871 comes from cubing the length conversion between inches and centimeters. Since 1 inch equals 2.54 cm, volume conversion requires cubing 2.54, giving 2.54 × 2.54 × 2.54 = 16.3871. This makes the volume units compatible.
Can I convert negative cubic inches to cubic centimeters?
Negative cubic inches represent volumes in reverse direction or theoretical values. The conversion formula works the same for negative numbers, multiplying by 16.3871, resulting in negative cc values. This is mathematically valid but rarely used physically.
Is there any difference between cc and ml?
No. Cubic centimeters (cc) and milliliters (ml) are equal in volume. One cc equals one ml exactly. The difference lies only in usage context: cc is used in medical or scientific fields, while ml is common in liquids measurement.
Why do medical prescriptions often use cc instead of ci?
Medical measurements use cc because it’s part of the metric system, which is more precise and standardized worldwide. Cubic inches are less common in medicine because imperial units aren’t as widely adopted for liquid or medication volumes.
How precise is the conversion to four decimals?
Rounding to four decimal places provides a good balance between precision and usability. The exact factor is 16.387064, but 16.3871 is close enough for most practical applications without causing significant error.
