How many arcseconds are in one arcminute?

There are exactly 60 arcseconds in one arcminute. So to convert arcseconds to arcminutes, divide by 60.

What is an arcsecond?

An arcsecond (symbol ″) is 1/3600 of a degree or 1/60 of an arcminute. It is used to measure very small angles in astronomy, geodesy, and high-precision navigation.

What is an arcminute?

An arcminute (symbol ′) is 1/60 of a degree. It is commonly used in navigation (nautical miles are defined by arcminutes of latitude), astronomy, and optics.

How do I convert arcseconds to arcminutes?

Divide the number of arcseconds by 60. For example, 120 arcseconds ÷ 60 = 2 arcminutes.

Can I convert negative arcseconds?

Yes. Negative arcseconds represent angles in the opposite direction (e.g. south of the equator or west of a reference meridian). The converter handles negative input correctly.

Summary

An arcsecond is 1/60 of an arcminute, making it the smallest of the three DMS (degrees, arcminutes, arcseconds) units. This converter takes any value in arcseconds and returns the equivalent in arcminutes using the exact ratio: arcminutes = arcseconds / 60. It also shows the full DMS breakdown for context.

How it works

Enter a value in arcseconds into the input field.
The converter divides your value by 60 to get arcminutes.
The result shows whole arcminutes and any remaining arcseconds.
Copy the arcminute result with one click.
