Arcseconds to degrees Converter

Enter the arcseconds, then press Calculate. The degrees stay hidden while you type.

Press Calculate after the entries are in.

What this angle conversion is for

Use this page when a measurement is written in arcseconds and the next step needs degrees. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

Multiply by the factor: 1 arcsecond = 0.00027778 degrees.

A worked example

10 arcseconds are 0.00277778 degrees. Multiply the result by the reverse factor if you want the original number back.

How to check it

Write the factor down, do the multiply on paper, and compare it with the result card. If you change a sentence on this page, edit the HTML file and reload. The form and this note live in the same file.

The reverse conversion is degrees to arcseconds. A nearby pair in the same units is arcseconds to mils. When the converted number is the input to a job, continue with the trigonometry.
