Pixels are a digital unit; centimeters are a physical unit. To relate them, we use DPI (dots per inch). This calculator assumes a common screen density of 96 DPI. With that assumption:
- 1 inch = 2.54 cm
- 1 inch = 96 px
- 1 px = 2.54 / 96 ≈ 0.026458 cm
- 1 cm ≈ 96 / 2.54 ≈ 37.80 px
How to use the CM ⇄ PX calculator

- Enter your value in the From box.
- The To value updates instantly—no need to press Convert.
- Use the Clear button to reset both fields.
Actual printed or on-screen size may differ if your device or document uses a different DPI.
