Convert between Arcsecond and Radian with step-by-step calculations.
Unit Information
Arcsecond (")
A unit of plane angle measurement equal to 1/60 of an arcminute or 1/3600 of a degree.
System: Conventional
Radian (rad)
The SI unit of plane angle.
System: SI
Conversion Process
This conversion uses Radian as the base unit. We'll first convert Arcsecond to Radian, then convert from Radian to Radian.
Step 1: Convert from Arcsecond to Radian
1 × 4.85e-6 = 4.85e-6
Result: 4.85e-6 Radian
Step 2: Convert from Radian to Radian
4.85e-6 × 1 = 4.85e-6
Result: 4.85e-6 Radian
Direct Conversion Factor
1 ÷ 206,264.81 = 4.85e-6
Direct conversion: 1 Arcsecond = 4.85e-6 Radian
Arcsecond (")
System: Conventional
Definition:1 arcsecond is 1/60 of an arcminute. $1" = \frac{1}{60}' = \frac{1}{3600}^{\circ} = \frac{\pi}{648000}$ radians.
Origin: Subdivision of the arcminute, based on sexagesimal system.
Common Usage: Used in fields requiring very high angular precision, such as astronomy (measuring parallax and apparent size of distant objects), cartography, geodesy, and satellite navigation.
Synonyms: second of arc, second
