- Start with your value in Mil/Thou. For example: 5 mil
- Multiply by the conversion factor: 5 x 254,000
- The result is: 1,270,000 Å
About Mil/Thou
A mil (or thou) is one thousandth of an inch, 25.4 micrometres. US manufacturing uses it for sheet, film and coating thickness.
Common uses: plastic film, PCB traces, coating thickness.
About Angstrom
The angstrom (Å) equals 10⁻¹⁰ metres, or 0.1 nanometres — roughly the diameter of a hydrogen atom, which is why it survives in crystallography and spectroscopy.
Common uses: crystallography, atomic physics, semiconductors.
