Unit conversion calculators
Unit conversions used in printed circuit board and circuit design. Convert between mil (thou) and mm, inches and mm, decibels and linear ratio, and copper weight in ounces to foil thickness. Enter a value and the result appears immediately.
Convert mm to mil
Calculator of convert mm to mil. 1 mm = 39.37 mil 1 mil is also referred to as 1 thou. In the United States and other countries where the yard-pound system is the mainstream, mil is often used in board design.
