Finger (unit)
A finger is any of several units of measurement that are approximately the width of an adult human finger, including:
The digit, also known as digitus or digitus transversus, dactyl or dactylus, or finger's breadth — of an inch or of a foot.
In medicine and related disciplines the fingerbreadth is an informal but widely used unit of measure.
In the measurement of distilled spirits, a finger of whiskey refers to the amount of whiskey that would fill a glass to the level of one finger wrapped around the glass at the bottom.
Another definition : "nearly an inch."
Finger is also the name of a longer unit of length used in cloth measurement, specifically, one eighth of a yard or 4 inches.
In English these units have mostly fallen out of use, apart from the common use in distilled drinks and drinking games.
