Quick Answer

Formula: Degree = Arcminute × 0.01667

Multiply any arcminute value by 0.01667 to get degree.

Reverse: Arcminute = Degree × 60

Worked Examples

One degree
60 ′ × 0.01667 = 1 °
60′ = 1°.
Half degree
30 ′ × 0.01667 = 0.5 °
30′ = 0.5°.
One arcminute
1 ′ × 0.01667 = 0.01667 °
1′ = 0.01667°.
Right angle
5400 ′ × 0.01667 = 90 °
5,400′ = 90°.

Optometrist

Assesses visual acuity in arcminutes — 20/20 vision resolves 1 arcminute features.

Telescope Operator

Describes field of view and pointing accuracy in arcminutes for optical telescopes.

Meteorologist

Measures solar and lunar angular diameters (~30-31 arcminutes) for eclipse calculations.

GIS Analyst

Works with geographic coordinates where position precision is often expressed in arcminutes.

Frequently Asked Questions

About Arcminute and Degree

Arcminute (′)

The arcminute (′) is 1/60 of a degree. The subdivision of degrees into 60 parts follows the Babylonian sexagesimal system. In astronomy, arcminutes have been used to describe angular separations since antiquity.

Arcminutes are used in astronomy (angular size of the Moon ≈ 31′), navigation (1 arcminute of latitude ≈ 1 nautical mile — the origin of the nautical mile definition), and ophthalmology (20/20 vision corresponds to resolving features 1 arcminute apart).

Interesting fact: The full Moon subtends about 31 arcminutes in the sky. Human visual acuity limit is about 1 arcminute — the basis of the 20/20 vision standard.

Degree (°)

The degree (°) divides a full circle into 360 equal parts. This system traces back to ancient Babylonian astronomy, which used a base-60 (sexagesimal) number system. The choice of 360 is practical: it is divisible by 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, and 120.

Degrees remain the dominant angle unit in everyday life, navigation, surveying, and most engineering disciplines. Compass bearings, latitude and longitude, and architectural drawings all use degrees.

Interesting fact: The Babylonians may have chosen 360 because they approximated the solar year as 360 days, making each day of travel correspond to one degree of the Sun's apparent annual motion around the sky.

About Arcminute to Degree Conversion

Converting arcminute to degree is essential in mathematics, physics, engineering, and surveying. Degrees are used in everyday contexts and navigation; radians are the standard in calculus and physics; gradians are common in European surveying. Having accurate conversions ensures correct results across disciplines.

Key reference: a right angle (90°) = 90 °. A full circle (360°) = 360 °. Reverse: 1 ° = 60 ′. Exact factor: 1 ′ = 0.01667 °.

All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
