What is a Mil/Thou and a Mile?
A mil (also known as a thou) is a unit of length equal to one thousandth of an inch (0.001 inches or 25.4 micrometers).
The mile, specifically the international statute mile, is a unit of length in the British imperial and United States customary systems. It is defined as exactly 5,280 feet, 1,760 yards, or approximately 1.609344 kilometers.
Note: The Mil/Thou is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Mile belongs to the imperial/US customary system.
History of the Mil/Thou and Mile
The unit originates from precision engineering and manufacturing where small tolerances are critical.
The mile originated from the Roman "mille passus", meaning "thousand paces" (where a pace was two steps). Its length varied considerably until Queen Elizabeth I of England standardized it as 5,280 feet in 1593. The international mile agreement of 1959 confirmed its definition based on the metric system.
