The conversion of 0.1 arcsecond to parsec results in approximately 4.8481 × 10⁻⁷ parsec.
Since 1 arcsecond equals about 4.8481 × 10⁻⁶ radians, and 1 parsec corresponds to 1 radian at a distance where the angle subtended is 1 radian, dividing arcseconds by 206265 gives the parsec value. Therefore, 0.1 arcsecond is 0.1 divided by 206265, leading to the stated value.
Conversion Result
0.1 arcsecond equals approximately 0.0000004848 parsec.

Conversion Formula
The formula to convert arcsecond to parsec relies on the relationship between angular measurement and distance. Since 1 arcsecond equals 1/206265 radians, dividing the arcsecond value by 206265 yields parsecs. For example, converting 0.1 arcsecond: 0.1/206265 = 4.8481 × 10⁻⁷ parsec, which represents the tiny angle in a distance unit.

Conversion Definitions
Arcsecond
An arcsecond is a unit of angular measurement equal to 1/3600 of a degree, used in astronomy to describe very small angles between celestial objects, enabling precise positioning and distance estimations over vast cosmic scales.
Parsec
A parsec is a distance measurement used in astronomy, approximately 3.086 × 10¹³ kilometers, defined as the distance at which one astronomical unit subtends an angle of one arcsecond, effectively linking angular separation to actual space distance.
Conversion FAQs
Why is 0.1 arcsecond equal to such a small fraction of a parsec?
Because 0.1 arcsecond is an extremely tiny angle, dividing it by 206265 radians per arcsecond results in a tiny parsec value, reflecting the large distances involved when measuring celestial objects with such small apparent angles.
Can I use the conversion factor for larger angles?
Yes, the same division by 206265 applies; larger arcsecond values simply produce proportionally larger parsec distances, making the method consistent across different measurements.
What are common uses for arcsecond to parsec conversions?
This conversion helps astronomers estimate the actual distances of stars and galaxies based on their observed angular separation, critical in distance mapping of the universe and understanding cosmic structures.
Does the conversion change if I use a different unit of angular measurement?
Yes, if you switch to degrees or radians, the conversion formula must adjust accordingly, but the arcsecond to parsec conversion specifically relies on the fixed relationship with radians divided by 206265.
