1 arcminute = 1/60 degree = 60 arcseconds ≈ 0.0167° ≈ 0.000291 radians
Symbol: ′ (prime) or arcmin
1 quadrant = 1/4 of a full circle = 90 degrees = π/2 radians ≈ 1.5708 radians
Key conversions:
- 1 quadrant = 90 degrees
- 1 quadrant = π/2 ≈ 1.5708 radians
- 1 quadrant = 100 gradians (or gons)
- 4 quadrants = 360 degrees (full circle)
- 2 quadrants = 180 degrees (straight angle)
Symbol: quad or Q (sometimes written as "right angle")
Note: The Arcminute is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Quadrant belongs to the imperial/US customary system.
Common Uses and Applications: arcminutes vs quadrants
Explore the typical applications for both Arcminute (imperial/US) and Quadrant (imperial/US) to understand their common contexts.
Common Uses for arcminutes
Astronomy: Measuring apparent sizes of celestial objects and their positions. Surveying: Land measurement and mapping precision. Navigation: GPS coordinates (latitude/longitude precision). Ophthalmology: Visual acuity testing (20/20 vision = 1 arcminute resolution).
When to Use quadrants
Coordinate Systems: Cartesian plane divided into four quadrants (I, II, III, IV). Navigation: Compass quadrants (NE, SE, SW, NW) for direction description. Astronomy: Celestial sphere divided into quadrants for star mapping. Geometry: Right angles and perpendicular measurements in construction and design.

What does 20/20 vision mean in arcminutes?
20/20 vision = ability to distinguish details subtending 1 arcminute at 20 feet
Visual acuity scale:
- 20/10 vision: 0.5 arcminutes (better than normal)
- 20/20 vision: 1 arcminute (normal)
- 20/40 vision: 2 arcminutes (needs glasses)
- 20/200 vision: 10 arcminutes (legally blind)
Better eyesight = smaller arcminute resolution.

What are the four quadrants in a coordinate plane?
Quadrant system divides the Cartesian plane using x and y axes:
Quadrant I (First): x > 0, y > 0
- Angles: 0° to 90° (or 0 to π/2 radians)
- Example point: (3, 4)
Quadrant II (Second): x < 0, y > 0
- Angles: 90° to 180° (or π/2 to π radians)
- Example point: (-3, 4)
Quadrant III (Third): x < 0, y < 0
- Angles: 180° to 270° (or π to 3π/2 radians)
- Example point: (-3, -4)
Quadrant IV (Fourth): x > 0, y < 0
- Angles: 270° to 360° (or 3π/2 to 2π radians)
- Example point: (3, -4)
Axes: Points on x or y axes are not in any quadrant.
Why is a right angle called a quadrant?
Etymology: "Quadrant" comes from Latin "quadrans" meaning "fourth part."
Historical context:
- A right angle is 1/4 of a full circle rotation
- Ancient navigational instruments called "quadrants" were quarter-circle shaped
- The term emphasizes the fractional relationship: 1 quadrant = 1/4 circle
Modern usage: While "right angle" is more common in everyday geometry, "quadrant" is still used in:
- Coordinate systems (Quadrant I, II, III, IV)
- Navigation and surveying
- Astronomy and celestial mechanics
- Mathematical analysis and calculus
The term "quadrant" emphasizes the measurement as a fraction of a circle, while "right angle" emphasizes the geometric perpendicularity (90°).
