What is a fingerbreadth?

A fingerbreadth is an informal, non-standard unit of length based on the width of an adult human finger, commonly used as a rough measure.

What is a mil (thou)?

A mil, also called a thou, is a unit equal to one thousandth of an inch, widely used in U.S. manufacturing and engineering for small thickness and tolerance measurements.

Why convert fingerbreadths to mils?

Converting fingerbreadths to mils helps translate approximate, informal measurements into precise units needed for technical applications such as manufacturing and engineering.
