What is a mil (thou)?

A mil, also known as a thou, is a unit of length equal to one thousandth of an inch, commonly used in manufacturing for small thicknesses and tolerances.

What is a fathom used for?

A fathom is a traditional unit of length equal to 6 feet, often used in nautical contexts to measure water depth and lengths of ropes or cables.

Why convert mils to fathoms?

Converting mils to fathoms helps translate very small engineering specifications into traditional nautical length units for maritime equipment and historical data.

Browser-based and accessible from any device.

Examples

Convert 1000 mil to fathoms results in 0.0138889 fath.
Convert 500 mil to fathoms results in 0.00694445 fath.

Common Use Cases

Specifying small thicknesses and clearances in manufacturing.
Interpreting maritime equipment dimensions using traditional length units.
Translating engineering measurements for nautical navigation and shipbuilding.
Combining manufacturing tolerances with nautical length scales.

Tips & Best Practices

Double-check unit selections before converting to ensure accuracy.
Use the tool for specialized contexts requiring conversion between mill-scale and nautical measurements.
Be aware of very small decimal results due to the size difference of units.
Use appropriate precision when working with small decimal values.

Limitations

Mils are extremely small compared to fathoms, so conversions yield tiny decimal numbers.
This conversion is less practical for common everyday conversions.
Mostly relevant in niche fields combining manufacturing and nautical environments.
