How to Convert Arcseconds to Angular Mils
To convert arcseconds to angular mils, multiply the angle by the following conversion ratio: 0.0049383 angular mils/second of arc.
Since one second of arc is equal to 0.0049383 angular mils, you can use this simple formula to convert:
The angle in angular mils is equal to the angle in arcseconds multiplied by 0.0049383.
For example, here's how to convert 5 arcseconds to angular mils using the formula above.
How Many Angular Mils Are in a Second of Arc?
There are 0.0049383 angular mils in a second of arc, which is why we use this value in the formula above.
Our second of arc to angular mil calculator automatically converts your angle measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Arcseconds and angular mils are both units used to measure angle. Keep reading to learn more about each unit.
What Is a Second of Arc?
A second of arc is a unit of angle equal to 1/3,600 of a degree (0.000277778 °). 1/3600 of a degree. [1]
The second of arc is classified as a standard unit of angle. Arcseconds can be abbreviated as ″; for example, 1 second of arc can be written as 1 ″.
When working with arcseconds (″) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, arcseconds (″) are widely used across fine-tolerance laboratory, analytical, and micro-scale angle measurements within international standard workflows, engineering documentation, and technical data sheets.
What Is an Angular Mil?
An angular mil is a unit of angle equal to 0.05625 degrees (°), the base unit for angle. Artillery & compass angle unit (6,400 mils = 360°, 1 mil = 0.05625°). [2]
The angular mil is classified as a standard unit of angle. Angular Mils can be abbreviated as mil; for example, 1 angular mil can be written as 1 mil.
When working with angular mils (mil) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, angular mils (mil) are widely used across standard angle applications within international standard workflows, engineering documentation, and technical data sheets.
When converting angle between arcseconds (″) and angular mils (mil), keep full floating-point precision (1 ″ = 0.0049383 mil; 1 mil = 202.5 ″) during intermediate calculations and round only the final angular mil figure to match your instrument tolerance.
