About this calculator
A mil (also called a “thou,” short for thousandth) is one thousandth of an inch, a unit used almost exclusively in manufacturing and engineering contexts where inch-based measurements are the norm — coating and film thickness, wire gauges, sheet metal, and machining tolerances.
This calculator converts a thickness in mils to micrometres (1 mil = 25.4 µm exactly) and to millimetres, letting engineers and quality control teams translate between the imperial mil and the metric micrometre that most international specifications, datasheets and measuring equipment use — a simple but essential conversion wherever a US-sourced spec meets a metric production line.
