About converting Arcminutes to Degrees
Arcminutes (′) and Degrees (°) are both units of angle, so converting between them is a single multiplication: multiply your Arcminutes figure by 0.01667. Ten Arcminutes comes to 0.1667 Degrees, and a hundred works out at 1.6667 Degrees.
Rule of thumb: going from Arcminutes to Degrees divides, so the figure always shrinks — it takes about 60 Arcminutes to make a single Degree. If your answer came out bigger, 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 a Degree?
The degree is the everyday unit of angle, and its division of the circle into 360 parts comes from Babylonian astronomy and the base-60 arithmetic that came with it. The number survived because it is unreasonably convenient: 360 divides evenly by 2, 3, 4, 5, 6, 8, 9, 10 and 12, so halves, thirds, quarters, fifths and sixths of a circle are all whole numbers of degrees. Nothing about it is natural or mathematically necessary — it is a human choice that stuck for thousands of years because the arithmetic is painless. Like the hectare, it is not an SI unit but is accepted for use with SI.
To put both in perspective: the full moon is about 31 arcminutes across, while a right angle is 90 degrees.
