Degree. The most common angle unit. A full circle = 360°.

Arc-minute. One sixtieth of a degree. Used in navigation, astronomy, and gun-sight scopes (a "MOA").

Frequently asked

What is the formula for converting Degree to Arc-minute?+
The formula is: 1 ° = 60 ′. Type any value into the calculator above and the result appears instantly.
How do I convert Arc-minute back to Degree?+
Click the swap button (⇄) above to go to the Arc-minute → Degree converter, or use the inverse formula derived from the one shown.
How accurate is the conversion?+
Conversion factors used here are exact rational values from NIST SP 811 and the BIPM SI brochure (e.g. 1 ft = 0.3048 m exactly, 1 lb = 0.45359237 kg exactly). Trailing-digit differences vs hand calculation come only from binary floating-point representation, never from the conversion factor itself.
Where do these conversion factors come from?+
Length and mass factors come from the 1959 international yard-and-pound agreement; SI base units (metre, kilogram, second, kelvin) come from the 2019 BIPM redefinition; energy and pressure factors are NIST SP 811 reference values. Each editorial section above lists the specific source for that category.
When would I use radians instead of degrees?+
Radians are the natural unit for mathematics — sine, cosine, and most calculus formulas expect radians. Degrees are the everyday unit (you say "turn 90°", not "turn π/2 rad"). Gradians are mostly used in surveying and some European school systems.
