1 ° = 60

Reverse Factor

1 = 0.0166667 °

Worked Example

Convert 25 Degrees to Arcminutes: 25 ° = 1500

About Degree (°)

A unit of plane angle equal to exactly 1/360 of a full rotation (= π/180 radians), inherited from ancient Babylonian astronomy's sexagesimal (base-60) number system circa 2000 BCE — the 360-degree convention reflects the ~360-day Babylonian solar year. Degrees are the universal everyday angle unit in non-scientific contexts: compass bearings and ship/aircraft heading per ICAO and IMO conventions (0° = magnetic north, 90° = east), latitude / longitude geographic coordinates per WGS84 (the GPS datum), machine-tool protractors and CNC G-code, GIS data (Esri ArcGIS, QGIS), CAD-software 2D-sketch dimensions (Autodesk Inventor, SolidWorks, Fusion 360, CATIA), and architectural drawings. Reference values: a right angle is exactly 90°, a straight line 180°, a full turn 360°, an equilateral triangle has 60° interior angles, a regular pentagon 108°, a regular hexagon 120°. Trigonometry education worldwide introduces sine and cosine in degrees before transitioning students to radians for calculus. Convert degrees to radians by multiplying by π/180 ≈ 0.01745.

About Arcminute ()

A unit of plane angle equal to exactly 1/60 of a degree (= π/10,800 rad ≈ 2.909 × 10⁻⁴ rad). Arcminutes are the standard sub-degree unit in observational astronomy (the angular diameter of Jupiter from Earth ranges 30-50 arcmin depending on orbit position; the Moon and Sun are both ~30 arcmin = 0.5° across), optometry and ophthalmology (visual acuity per Snellen test: 20/20 vision corresponds to resolving a black bar with a 1-arcmin gap at 20 feet — the universally-used definition of 'normal' visual acuity), surveying and geodesy (USGS topographic-map quad sheets are 7.5 arcmin × 7.5 arcmin), and aviation/maritime navigation. The arcminute has a direct distance interpretation in navigation: one arcminute of latitude along any meridian equals exactly one international nautical mile (1,852 m by the 1929 IHB definition) — the historic basis for both units. Symbol ′ (prime); not to be confused with the foot-symbol ′.

Frequently Asked Questions

How do I convert Degrees to Arcminutes?

A unit of plane angle equal to exactly 1/360 of a full rotation (= π/180 radians), inherited from ancient Babylonian astronomy's sexagesimal (base-60) number system circa 2000 BCE — the 360-degree convention reflects the... To convert Degrees to Arcminutes, multiply by 60. For example, 25 ° equals 1500 ′.

How many Arcminutes are in 1 Degree?

There are 60 Arcminutes in 1 Degree.

How many Degrees are in 1 Arcminute?

There are 0.0166667 Degrees in 1 Arcminute.

What is the formula for Degree to Arcminute conversion?

The formula is: multiply by 60. This means 1 ° = 60 ′.

Is a Degree bigger than a Arcminute?

No. One Degree is smaller than one Arcminute because 1 ° equals 60 ′, which is greater than 1.

When do you need to convert between Degrees and Arcminutes?

A unit of plane angle equal to exactly 1/60 of a degree (= π/10,800 rad ≈ 2. Degree and Arcminute are both angle units, so conversion comes up whenever one source of information uses one unit and another uses the other — a classic cross-reference challenge in engineering, trade, travel, and everyday life.
