What is a mil (thou)?

A mil, also called a thou, is a length unit equal to one thousandth of an inch, commonly used in U.S. manufacturing and engineering.

What is a femtometer used for?

A femtometer is used to measure extremely small distances like atomic nuclei sizes and interactions in nuclear and particle physics.

Why convert mils to femtometers?

Conversions are needed to relate practical mechanical dimensions to atomic or nuclear scale lengths, especially in advanced physics or nanotechnology.
