1 gon = 1/400 of a full circle = 0.9 degrees = 0.01571 radians
Key conversions:
- 100 gons = 90 degrees (right angle)
- 200 gons = 180 degrees (straight angle)
- 400 gons = 360 degrees (full circle)
- 1 gon = 0.9° = π/200 radians
Alternative names: Gradian, grad, grade (same unit, different names)
1 arcsecond = 1/60 arcminute = 1/3600 degree ≈ 0.000278° ≈ 0.00000485 radians
Symbol: ″ (double prime) or arcsec
Key conversions:
- 60 arcseconds = 1 arcminute
- 3600 arcseconds = 1 degree
- 1 arcsecond ≈ 4.848 × 10⁻⁶ radians
Note: The Gon is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Arcsecond belongs to the imperial/US customary system.
Common Uses and Applications: gons vs arcseconds
Explore the typical applications for both Gon (imperial/US) and Arcsecond (imperial/US) to understand their common contexts.
Common Uses for gons
Surveying: Land surveys and topographic mapping in Europe, especially France, Germany, Switzerland - THE standard in continental Europe. Civil Engineering: Construction projects, road gradients, slope calculations - preferred by engineers trained in metric system. Military: Artillery targeting and ballistics in some European armies - standardized for ballistics calculations. Cartography: Map making and coordinate systems in countries using metric system - seamless with metric philosophy.
When to Use arcseconds
Astronomy: Measuring star positions, planetary motion, stellar parallax, and telescope resolution. Surveying: High-precision land measurements and geodetic surveys. GPS Systems: Coordinate precision (1 arcsecond ≈ 30 meters at equator). Optics: Telescope and microscope angular resolution specifications.
Additional Unit Information
About Gon (gon)
How do I convert gons to degrees?
Formula: Degrees = Gons × 0.9 (or Gons × 9/10)
Examples:
- 100 gons = 90°
- 200 gons = 180°
- 400 gons = 360°
- 50 gons = 45°
- 1 gon = 0.9°
How do I convert degrees to gons?
Formula: Gons = Degrees ÷ 0.9 (or Degrees × 10/9)
Examples:
- 90° = 100 gons
- 45° = 50 gons
- 180° = 200 gons
- 360° = 400 gons
- 1° = 1.111 gons
Why use gons instead of degrees?
Decimal convenience: Base-10 system makes calculations easier without fractions.
Advantages:
- Right angle = 100 (clean decimal)
- Easier to divide: 400 ÷ 4 = 100, 400 ÷ 8 = 50
- Better for percentage calculations
- Aligns with metric system philosophy
- Simpler mental arithmetic
Metric integration: Designed to work with decimal measurement system used in surveying.
Are gons and gradians the same?
Yes, identical units with different names:
- Gon: Modern term, ISO standard (ISO 31-1)
- Gradian: Traditional term, still widely used
- Grad: Abbreviated form, common in calculators
- Grade: French term (same unit)
All refer to 1/400 of a circle. The term "gon" is preferred in modern standards to avoid confusion with other uses of "grade" (like road gradients or academic grades).
Symbol variations: gon, grad, or superscript "g" (e.g., 50ᵍ)
About Arcsecond (″)
How do I convert arcseconds to degrees?
Formula: Degrees = Arcseconds ÷ 3600
Examples:
- 3600 arcseconds = 1°
- 1800 arcseconds = 0.5°
- 60 arcseconds = 1 arcminute = 0.0167°
- 1 arcsecond ≈ 0.000278°

How do I convert arcseconds to arcminutes?
Formula: Arcminutes = Arcseconds ÷ 60
Examples:
- 60 arcseconds = 1 arcminute
- 120 arcseconds = 2 arcminutes
- 30 arcseconds = 0.5 arcminutes
- 3600 arcseconds = 60 arcminutes = 1°

How big is 1 arcsecond on Earth's surface?
At the equator: 1 arcsecond ≈ 30.9 meters ≈ 101 feet
Latitude (north-south): Always ≈ 30.9 m per arcsecond Longitude (east-west): Varies by latitude:
- Equator: 30.9 m
- 45° latitude: 21.9 m
- 60° latitude: 15.5 m
- 80° latitude: 5.4 m
This is why GPS coordinates to arcsecond precision give location within ~30 meters.
What is stellar parallax in arcseconds?
Stellar parallax is the apparent shift in a star's position as Earth orbits the Sun, measured in arcseconds.
Formula: Distance (parsecs) = 1 / Parallax (arcseconds)
Examples:
- Proxima Centauri: 0.768 arcseconds → 1.30 parsecs (4.24 light-years)
- Sirius: 0.379 arcseconds → 2.64 parsecs (8.6 light-years)
- Alpha Centauri A: 0.742 arcseconds → 1.35 parsecs (4.37 light-years)
- Barnard's Star: 0.547 arcseconds → 1.83 parsecs (5.96 light-years)
The parsec (pc) unit was defined as the distance at which 1 AU creates 1 arcsecond parallax.
