10 µm	0.000394 in
100 µm	0.003937 in
1000 µm	0.039370 in
10000 µm	0.393701 in
25400 µm	1.000000 in

Overview & Capabilities

Converting micrometers (µm / microns) to decimal inches (in) is essential for semiconductor process engineers, microchip cleanroom technicians, and micro-electromechanical (MEMS) fabricators. In microelectronics manufacturing, 25.4 micrometers equals exactly 0.001 inches (one mil). When measuring photolithography wafer trace widths (e.g. 25.4 µm = 1 mil, or 50.8 µm = 2 mils) or HEPA air filtration particles, dividing micrometers by 25,400 provides exact decimal inches.

Tutorial

How to Use

01

Enter the microelectronic feature size in Micrometers (µm).

02
