This converter allows you to convert arcseconds [″] to radians [rad] or radians [rad] to arcseconds [″]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.
Convert arcseconds to radians
There are two simple ways to convert arcseconds [″] to radians [rad]. In the first calculation method, the value in arcseconds [″] is divided by the rounded conversion factor of 206,264.8062. The second method multiplies the value in arcseconds [″] by the rounded conversion factor of 4.848 * 10-6.
- Radians [rad] ≈ arcseconds [″] ÷ 206,264.8062
- Radians [rad] ≈ arcseconds [″] * 4.848 * 10-6
However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of arcseconds [″] to radians [rad] can be achieved using the following calculation method.
- Radians [rad] = arcseconds [″] * π ÷ 648,000
Convert radians to arcseconds
Converting radians [rad] to arcseconds [″] is easy and can be done in two ways. The first method involves multiplication, in which the value in radians [rad] is multiplied by the rounded conversion factor of 206,264.8062. The second variant is a division. Here, the value in radians [rad] is divided by the rounded conversion factor of 4.848 * 10-6.
- Arcseconds [″] ≈ radians [rad] * 206,264.8062
- Arcseconds [″] ≈ radians [rad] ÷ (4.848 * 10-6)
However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of radians [rad] to arcseconds [″] can be achieved using the following calculation method.
- Arcseconds [″] = radians [rad] * 648,000 ÷ π
