What is a Mil/Thou and a Nautical 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).
A nautical mile is a unit of length used in marine and air navigation. It is defined as exactly 1,852 meters.
Note: The Mil/Thou is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Nautical Mile belongs to the imperial/US customary system.
History of the Mil/Thou and Nautical Mile
The unit originates from precision engineering and manufacturing where small tolerances are critical.
The nautical mile originated from the length of one minute of arc of latitude along any meridian. It was standardized internationally in 1929.

Is 'mil' short for millimeter?
No, 'mil' is short for the Latin 'mille', meaning thousandth (of an inch). It is not an abbreviation for millimeter (mm).
What does 'thou' mean in this context?
'Thou' is another common name for a mil, also meaning one thousandth (of an inch). It is frequently used in engineering and machining.
About Nautical Mile (NM)
Why is a nautical mile different from a statute mile?
A statute mile (used on land, 1609.344 meters) is based on historical measurements. A nautical mile (1852 meters) is derived from the Earth's circumference (1 minute of latitude) and simplifies navigation calculations.
How many feet are in a nautical mile?
One nautical mile is approximately 6076.115 feet.
What is a knot in relation to a nautical mile?
A knot is a unit of speed equal to one nautical mile per hour. It's commonly used in maritime and aviation contexts.
