Centimetres to pixels at 72 DPI
At 72 DPI, one centimetre is 28.35 pixels. Multiply centimetres by 28.346 to get pixels.
The formula
Pixels = centimetres ÷ 2.54 × 72. There are 2.54 centimetres in an inch, so one centimetre is 72 ÷ 2.54 = 28.346 pixels. Round the result to a whole pixel.

72 DPI is the old screen convention: early Macintosh displays showed 72 pixels to the inch, matching the 72 points in an inch of type. Many image files still carry a 72 DPI tag for that reason.
