Cubic inches to cubic centimetres – convert in³ to cm³
Convert cubic inches to cubic centimetres (in³ to cm³) for engine sizes, packaging, 3D printing and machining. This page opens the main volume converter with in³ → cm³ pre-selected.
Quick reference: in³ to cm³
Because 1 in = 2.54 cm exactly, the volume conversion is: 1 in³ = 16.387064 cm³.
| Cubic inches (in³) | Cubic centimetres (cm³, approx.) |
|---|---|
| 1 in³ | 16.39 cm³ |
| 10 in³ | 163.9 cm³ |
| 50 in³ | 819 cm³ |
| 100 in³ | 1,639 cm³ |
| 150 in³ | 2,458 cm³ |
Where are in³ and cm³ used?
in³ is common in imperial contexts for engine displacement (especially older specs), small packaging volumes and machining.
cm³ is the metric equivalent used in modern engine sizes (cc), medicine dosage volumes and scientific work.
Why convert in³ to cm³?
- Comparing older imperial engine sizes with modern cc ratings.
- Converting packaging or mould cavity volumes into metric units.
- Working between imperial CAD drawings and metric manufacturing.
- Translating technical data sheets into SI-based documentation.
in³ to cm³ FAQ
- Is 1 in exactly 2.54 cm?
- Yes, by definition. That makes the in³ to cm³ conversion exact as well.
- Why do engines use “cc” instead of cm³?
- “cc” is just shorthand for cubic centimetres. 1 cc = 1 cm³ exactly.
- Can I estimate quickly?
- Multiplying in³ by 16 gives a quick rough cm³ value; the converter returns the precise figure using 16.387064.
