About converting Arcminutes to Arcseconds
Arcminutes (′) and Arcseconds (″) are both units of angle, so converting between them is a single multiplication: multiply your Arcminutes figure by 60. Ten Arcminutes comes to 600 Arcseconds, and a hundred works out at 6,000 Arcseconds.
Rule of thumb: going from Arcminutes to Arcseconds multiplies, so the figure always grows — one Arcminute is already 60 Arcseconds. If your answer came out smaller, you have the conversion the wrong way round.
What is an Arcminute?
The arcminute subdivides the degree in base 60, exactly as the minute subdivides the hour — the matching names are not a coincidence but shared Babylonian ancestry. It is the traditional unit of latitude and longitude, where position is written as degrees, minutes and seconds, and that convention pays off at sea: one minute of latitude is one nautical mile, so a navigator can lift distance straight off a chart’s edge. It is also about the limit of human eyesight — a healthy eye resolves detail roughly an arcminute across, which is the standard "20/20 vision" is built around.
What is an Arcsecond?
The arcsecond is a sixtieth of an arcminute, and it is where angle measurement becomes astronomy. The apparent width of a planet, the separation of a double star and the resolving power of a telescope are all quoted in arcseconds, and Earth’s atmosphere smears ground-based images to roughly an arcsecond of "seeing" — which is precisely why observatories go up mountains and telescopes go into orbit. It is a startlingly small angle: about what a coin subtends from several kilometers away. Precision optics, satellite pointing and surveying instruments all work in arcseconds or finer.
To put both in perspective: the full moon is about 31 arcminutes across, while atmospheric blur limits most ground telescopes to about one arcsecond.

Frequently asked questions
How many Arcseconds are in one Arcminute?
There are 60 Arcseconds in one Arcminute.
How do I convert Arcminutes to Arcseconds?
Multiply the number of Arcminutes by 60. For example, 10 Arcminutes = 600 Arcseconds.
What is 100 Arcminutes in Arcseconds?
100 Arcminutes is equal to 6,000 Arcseconds.
How do I convert Arcseconds to Arcminutes?
Multiply the Arcseconds value by 0.01667 (or divide by 60).
Is this Arcminutes to Arcseconds conversion exact?
The definition is exact — Arcminutes and Arcseconds are both fixed against the same base by international agreement — but the decimal shown here is rounded for readability, because the true ratio does not terminate. For engineering or scientific work, carry more decimal places than this page displays.
