About the Pixels to Centimetres
Pixels have no fixed physical size: how big a pixel is depends on the resolution (DPI or PPI). On screens and in CSS, 96 pixels make one inch, so 1 cm ≈ 37.8 px. In print at 300 DPI, 1 cm = 118.1 px.
Set the DPI that matches what you're doing, then enter the value to convert. The table below shows common values at 72, 96, 150 and 300 DPI.
