About the Millimeters to Pixels conversion
A millimeter is a metric length; converting it to pixels goes through inches. Divide the millimeter value by 25.4 to get inches, then multiply by the DPI to get pixels.
At the 96 DPI CSS reference, 25.4mm is 96px, so 1mm is about 3.78px. For print, set the DPI to 150 or 300 to compute the correct pixel dimensions.
Use this millimeters to pixels converter when a precise metric measurement needs to become pixel dimensions for a design tool or print export.
