Examples
1
Consider that a microscope's fine adjustment is set to 30 arc seconds for detailed observation. Convert this angle from seconds to Milli-radians.
Answer:
Given:
The angle in seconds is:
Angle(Seconds) = 30
Formula:
The formula to convert angle from seconds to milli-radians is:
Angle(Milli-radians) = Angle(Seconds) × π / 648
Substitution:
Substitute given weight Angle(Seconds) = 30 in the above formula.
Angle(Milli-radians) = 30 × 3.14159265359 / 648
Angle(Milli-radians) = 0.1454
Final Answer:
Therefore, 30 " is equal to 0.1454 mrad.
The angle is 0.1454 mrad, in milli-radians.
2
Consider that a telescope's alignment needs to be within 20 arc seconds for accurate tracking. Convert this angle from seconds to Milli-radians.
Answer:
Given:
The angle in seconds is:
Angle(Seconds) = 20
Formula:
The formula to convert angle from seconds to milli-radians is:
Angle(Milli-radians) = Angle(Seconds) × π / 648
Substitution:
Substitute given weight Angle(Seconds) = 20 in the above formula.
Angle(Milli-radians) = 20 × 3.14159265359 / 648
Angle(Milli-radians) = 0.09696273622
Final Answer:
Therefore, 20 " is equal to 0.09696273622 mrad.
The angle is 0.09696273622 mrad, in milli-radians.

Seconds
Seconds of arc, often simply called arcseconds, are a further subdivision of minutes of arc, with 60 seconds in one minute. This small unit is used for extremely precise angular measurements, such as those needed in astronomy, optics, and surveying, where even minute differences in angle can be significant.
Milli-radians
Milli-radians (mrad) are a unit of angular measurement equal to one-thousandth of a radian. This small unit is used in fields such as ballistics, gunnery, and optics, where precise angular measurements are critical. Milli-radians allow for the calculation of minute angular displacements, distances, and target adjustments.
