Revolutions to arcseconds Converter

Enter the revolutions, then press Calculate. The arcseconds 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 revolutions and the next step needs arcseconds. 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 revolution = 1,296,000 arcseconds.

A worked example

10 revolutions are 1.296e+07 arcseconds. 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 arcseconds to revolutions. A nearby pair in the same units is degrees to arcseconds. When the converted number is the input to a job, continue with the trigonometry.
