Understanding Gon: The Surveyor's Angle Unit

The gon — also referred to as a gradian or grade — is a unit of angular measurement that divides a full circle into exactly 400 equal parts. Originating from the French metric system during the late 18th century, the gon was specifically designed to simplify trigonometric calculations in surveying, civil engineering, and geodesy. Unlike the degree system, where a right angle equals 90°, a right angle in the gon system is a clean 100 gon, making arithmetic and navigation computations considerably more straightforward.

Today, gon measurements are widely used across European surveying traditions and professional-grade total stations, theodolites, and GPS instruments. Understanding how to convert gon to degrees (multiply by 0.9), radians (multiply by π/200), arcminutes, arcseconds, or other units is essential for cross-disciplinary work. For instance, 400 gon equals 360 degrees, one full revolution, or 2π radians. The mil unit, commonly used in military applications, relates to gon through a factor that varies by national standard. Whether you are digitizing land parcels, setting out construction baselines, or programming robotic surveying instruments, accurate gon conversions are critical. Our bulk gon converter handles all these conversions instantly, supporting precision from 0 to 10 decimal places, real-time input validation, and CSV export — making it an indispensable tool for professionals and students working with angular data.

Frequently Asked Questions

Common questions about gon and angle unit conversions.

A gon, also known as a gradian or grade, is an angular unit where a full circle equals 400 gon. A right angle is exactly 100 gon. It was introduced during the French metric revolution to simplify surveying math and is still widely used in European geodesy and civil engineering instruments.
1 gon = 0.9 degrees. Since a full circle spans 360 degrees and 400 gon, each gon represents 360 ÷ 400 = 0.9°. Conversely, 1 degree = 1.1111… gon (10/9 gon).
Multiply the gon value by π/200. So 1 gon ≈ 0.015708 radians. For example, 100 gon = π/2 radians (a right angle), and 400 gon = 2π radians (a full circle).
Yes, gon and grad (gradian) are identical units. The name "gon" is more commonly used in ISO standards and professional surveying contexts, while "grad" and "gradian" are used in general mathematics and some calculator environments. The conversion factor is 1:1.
Yes! Negative gon values represent angles measured in the clockwise direction (or below a reference line). The converter handles negative values correctly — the sign is preserved in all output conversions.
A mil (military mil) is used primarily in artillery and military navigation. The NATO standard defines 6400 mils per full circle. Therefore, 1 gon = 6400/400 = 16 mils. Different national standards (Soviet, Swedish) use slightly different mil definitions; this converter uses the NATO standard.
All conversions are performed using JavaScript's IEEE 754 double-precision floating-point arithmetic, which provides approximately 15–17 significant digits of accuracy. You can control the displayed precision from 0 to 10 decimal places using the precision slider.
