The conversion of 0.1 arcsecond to parsec results in approximately 4.8481 x 10-7 parsec.
Table of Contents
Since 1 arcsecond equals 4.8481 x 10-6 parsec, multiplying this value by 0.1 gives us the result. This means that a very tiny angle of 0.1 arcsecond corresponds to a fraction of a parsec, used in measuring astronomical distances with high precision.

Conversion Formula
The formula to convert arcsecond to parsec is: parsec = arcsecond * 4.8481e-6. This works because 1 arcsecond is defined as 1/3600 degree, and 1 degree corresponds to about 4.8481 x 10-6 parsec based on the standard astronomical conversions. Multiplying arcseconds by this number gives the distance in parsecs.
For example, converting 1 arcsecond: 1 * 4.8481e-6 = 4.8481e-6 parsec. For 0.1 arcsecond: 0.1 * 4.8481e-6 = 4.8481e-7 parsec. This proportional relation makes it easy to switch between the two units.
Conversion Example
- Convert 0.5 arcsecond:
- Multiply 0.5 by 4.8481e-6.
- 0.5 * 4.8481e-6 = 2.42405e-6 parsec.
- This is the distance in parsecs for 0.5 arcsecond.
- Convert 2 arcseconds:
- Multiply 2 by 4.8481e-6.
- 2 * 4.8481e-6 = 9.6962e-6 parsec.
- So, 2 arcseconds equals approximately 9.6962e-6 parsec.
- Convert 10 arcseconds:
- 10 * 4.8481e-6 = 4.8481e-5 parsec.
- Therefore, 10 arcseconds corresponds to about 4.8481e-5 parsec.
- Convert 0.01 arcsecond:
- 0.01 * 4.8481e-6 = 4.8481e-8 parsec.
- This small angle equals roughly 4.8481e-8 parsec.

Conversion Definitions
Arcsecond: An arcsecond is a unit of angular measurement equal to 1/3600th of a degree, used in astronomy to describe very small angles such as the apparent size of distant celestial objects. It helps quantify minute differences in positions in the sky.
Parsec: A parsec is a distance measurement used mainly in astronomy, equal to about 3.086 x 1016 meters, defining how far light travels in one second over a year. It is based on the parallax angle of one arcsecond, used to measure cosmic distances.
Conversion FAQs
How precise is the conversion from 0.1 arcsecond to parsecs?
The conversion provides an accurate approximation because it relies on well-established astronomical constants. For practical purposes, the value of 4.8481 x 10-7 parsec per arcsecond ensures minimal error in typical measurements, but very high-precision work may require further correction.
Can I use this conversion for angles larger than 0.1 arcsecond?
Yes, the same formula applies regardless of the angle’s size. Simply multiply the angle in arcseconds by 4.8481 x 10-6 to get the distance in parsecs. Larger angles will result in proportionally larger parsec values, making the method universally applicable.
Why is the conversion factor 4.8481e-6?
This factor comes from the relationship between degrees, arcseconds, and parsecs. Since 1 degree equals 3600 arcseconds, and 1 parsec is defined based on the parallax of 1 arcsecond, the constant converts an angular measurement directly into a distance measurement in parsecs.
Is the parsec unit used in everyday astronomy measurements?
While parsecs are common in scientific literature for expressing distances to stars and galaxies, in everyday astronomy, light-years are often used for simplicity. Nonetheless, parsecs remain essential for precise distance calculations involving very distant objects.
