ENGINEERING TOOLS / UNIT CONVERTER
PCB dimensional unit converter
Convert ceramic, copper and layout dimensions between millimeters, micrometers, mils, inches, centimeters and meters.
Unit conversion does not change a dimension’s tolerance or measurement uncertainty. A mil is one thousandth of an inch, not a millimeter.
Calculation method
1 inch = 25.4 mm; 1 mil = 0.0254 mm; 1 µm = 0.001 mm.
How to use the result
Unit conversion does not change a dimension’s tolerance or measurement uncertainty. A mil is one thousandth of an inch, not a millimeter.
