What is a Planck length?

The Planck length is a natural length scale in physics defined by fundamental constants, representing the scale where quantum gravity effects become significant.

What is a mil or thou?

A mil, or thou, is a unit of length equal to one thousandth of an inch, typically used in U.S. manufacturing to specify small thicknesses and tolerances.

Can I use this conversion for precise manufacturing measurements?

No, this conversion is intended for conceptual comparisons only, as the Planck length is far too small to measure or apply directly in manufacturing.
