calculating pixel size from ppi

Question

I need some help to verify that i have made my calculations correct.

I want to determine number of pixels in the span of 13.6 millimeters for a specific device that is 224,17 pixels per inch.

( if 1 inch = 224.17ppi therefor: 1 centimeter = 569.39ppcm therefor: 1 millimeter = 5.69 ppmm )

I calculate 13.6mm = 77.35 pixels

(224.17 pixels / 1 inch) * (1 inch / 25.4 mm) * 13.6 mm = 120 pixels

centimeters are smaller than inches; that's one obvious place where your initial math is off. – andi Feb 06 '17 at 16:27
