Convert mil to micrometer
Please provide values below to convert mil [mil, thou] to micrometer [µm], or Convert micrometer to mil.
1 mil, thou = 25.4 µm. To convert mil to micrometer, multiply the value by 25.4; to go the other way, divide by it (1 µm = 0.0393700787402 mil, thou). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mil, thou = 25.4 µm
- 1 µm = 0.0393700787402 mil, thou
- 10 mil, thou = 254 µm
- 100 mil, thou = 2540 µm
How to Convert Mil to Micrometer
1 mil, thou = 25.4 µm
Example: convert 15 mil, thou to µm:
15 mil, thou = 15 × 25.4 µm = 381 µm

Mil
A mil, also known as a thou, is a unit of length equal to one-thousandth of an inch.
History/Origin
The mil was introduced in the 19th century as a convenient unit for fine measurements in engineering and manufacturing.
Current Use
The mil is still used in some manufacturing and engineering contexts, particularly in the United States, for specifying the thickness of materials like paper and wire.
Micrometer
A micrometer, also known as a micron, is a unit of length equal to one-millionth of a meter.
History/Origin
The term "micron" and the symbol µ were officially declared obsolete by the General Conference on Weights and Measures (CGPM) in 1967, and "micrometer" became the official term.
Current Use
The micrometer is a common unit for measuring the wavelength of infrared radiation, as well as the size of biological cells and bacteria. It is also widely used in technology and engineering.
