Pixel to Quarter-Millimeter (px to Q)
Convert px to Q — Typography converter
One pixel equals 1.058333 Q, so to convert pixels to quarter-millimeters you multiply the value by 1.058333. A pixel is larger than a quarter-millimeter — going the other way, 1 Q = 0.94488189 px. For example, 10 px = 10.583333 Q and 50 px = 52.916667 Q.
1 px = 1.058333 Q

Why 16 px equals 12 pt
Two fixed definitions drive every conversion on this page. A typographic point is 1/72 of an inch. A CSS reference pixel is 1/96 of an inch. That makes 1 px exactly 0.75 pt, and 16 px exactly 12 pt — which is why 16 px became the default body size on the web: it matches the 12 pt that print had already settled on.
A pica is 12 points, so 1 pica = 16 px. InDesign, Quark and most print workflows measure column widths and gutters in picas; CSS has no pica unit, so those measurements have to be converted before they reach a stylesheet. On this page, 1 px = 1.058333 Q.
The CSS pixel is a reference unit, not a hardware pixel. On a 2× or 3× display, one CSS px still occupies 1/96 inch of visual space — the device simply renders it with more physical pixels. Converting CSS px to physical pixels requires the device pixel ratio, which is a separate calculation from anything on this page.
