What is a Radian?

A radian is the standard SI unit of angular measure, defined as the angle formed when the arc length equals the radius. One full rotation is 2π radians.

What is a Arcsecond?

An arcsecond is a unit of angular measurement equal to 1/3600 of a degree. Commonly used in astronomy for expressing tiny angles.

Conversion Formula

To convert Radian to Arcsecond, use the formula:

Arcsecond = Radian × (1.0000000000e+0 / 4.8481368111e-6)

This formula works by converting Radian into radians as the base unit, then converting that result into Arcsecond. It ensures high-precision conversion.

Example: Convert 10 Radian to Arcsecond:
10 × (1.000000e+0 ÷ 4.848137e-6) = 2062648.062 Arcsecond
