Arcseconds to Degrees Converter
How to convert arcseconds to degrees
degrees = arcseconds ÷ 3,600
To convert arcseconds to degrees, divide the number of arcseconds by 3,600.
1″ = 0.000277777778°
Examples
- One degree: 3,600″ ÷ 3,600 = 1°
- One arcminute: 60″ ÷ 3,600 = 0.0166666667°
Good to know
One degree is exactly 3600 arcseconds. Coordinates written as degrees, minutes and seconds convert to decimal degrees by dividing the seconds by 3600 and the minutes by 60.
