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)
NATO mil: 1 mil = 1/6400 of a circle ≈ 0.05625 degrees ≈ 0.000982 radians
Alternative definitions:
- NATO/US military: 6400 mils = 360° (standard)
- Soviet/Russian: 6000 mils = 360°
- Swedish: 6300 mils = 360°
- True milliradian: 1000 milliradians = 1 radian (6283.2 mils = 360°)
Key conversions (NATO mil):
- 1 mil ≈ 0.05625 degrees
- 1600 mils = 90 degrees (right angle)
- 3200 mils = 180 degrees
- 6400 mils = 360 degrees (full circle)
Note: The Gon is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Mil belongs to the imperial/US customary system.
Common Uses and Applications: gons vs mils
Explore the typical applications for both Gon (imperial/US) and Mil (imperial/US) to understand their common contexts.
Common Uses for gons
Surveying: Land surveys and topographic mapping in Europe, especially France, Germany, Switzerland. Civil Engineering: Construction projects, road gradients, slope calculations. Military: Artillery targeting and ballistics in some European armies. Cartography: Map making and coordinate systems in countries using metric system.
When to Use mils
Military Artillery: Gun laying, indirect fire calculations, ballistic corrections. Sniper Operations: Scope adjustments, windage, elevation corrections for long-range shooting. Rangefinding: Estimating target distance using known target size and angular measurements. Fire Control Systems: Tank gunnery, naval artillery, anti-aircraft targeting.
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 Mil (mil)
How do I convert mils to degrees?
Formula (NATO mil): Degrees = Mils × (360/6400) = Mils × 0.05625
Examples:
- 100 mils = 5.625°
- 1600 mils = 90°
- 3200 mils = 180°
- 6400 mils = 360°
- 1 mil ≈ 0.05625°
How do mils work for range estimation?
Fundamental principle: At 1000 meters, 1 mil subtends approximately 1 meter.
Range formula: Range (m) = (Object size in meters × 1000) ÷ Object size in mils
Common target sizes:
- Adult human: ~1.7m tall
- Doorway: ~2m tall
- Car: ~4m long, ~1.5m tall
- Tank: ~3m wide, ~2.5m tall
- Shipping container: ~12m long, ~2.5m tall
Example: If a 2-meter tall object appears to be 4 mils in your scope, it's 500 meters away: (2 × 1000) ÷ 4 = 500m
What's the difference between NATO mils and Russian mils?
NATO/US Military: 6400 mils = 360° (1 mil = 0.05625°)
- Used by NATO countries, US military, most Western forces
- Divides circle into 6400 parts (approximation of 2000π)
Soviet/Russian: 6000 mils = 360° (1 mil = 0.06°)
- Used by Russian and former Soviet militaries
- Divides circle into 6000 parts (decimal convenience)
Practical impact: Russian mil is slightly larger. Always verify which system your equipment uses. Most modern Western civilian and military equipment uses NATO mils.
How do mil-dot scopes work?
Mil-dot reticle: Crosshairs marked with dots spaced 1 mil apart (center-to-center).
Applications:
- Range estimation: Measure target size in mils, calculate distance
- Holdover: Use lower dots for bullet drop compensation
- Windage: Use horizontal dots for wind drift correction
- Moving targets: Lead calculation using mil spacing
Example: Target (1.7m tall person) covers 2 mil-dots → Range = (1.7 × 1000) ÷ 2 = 850 meters
Modern variations: Mil-dot, mil-hash, Christmas tree reticles all use milliradian spacing for calculations.
