Millimeters (mm)

Definition

A millimeter (mm) is a metric unit of length equal to one thousandth of a meter (0.001 m). There are 10 millimeters in a centimeter.

History

The millimeter derives from the metric system established in France in 1795. It became widely used in engineering and manufacturing as precision requirements increased during the Industrial Revolution.

Current use

Millimeters are standard in engineering drawings, precision machining, medical measurements (tumor sizes), rainfall measurement, and small-scale construction specifications worldwide.

Mils (thousandths of an inch)

Definition

A mil (also called a thou) is an imperial unit of length equal to one thousandth of an inch (0.001 in or approximately 0.0254 mm).

History

The mil originated in manufacturing and engineering in English-speaking countries as a practical unit for measuring very thin materials. The name 'thou' derives from 'thousandth of an inch'.

Current use

Mils are used in manufacturing for measuring wire diameter, sheet metal thickness, printed circuit board (PCB) trace widths, paint and coating thickness, and plastic film thickness.
