gradian to turn
Convert gradian (gon) to turn (rev). Use an editable angle converter, conversion formula, and reference table.
1 gon = 0.0025 rev
Conversion formula
One gradian equals 0.0025 turn. Multiply your value in gradian by this factor to get turn. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 gradian:5 × 0.0025 = 0.0125 rev

About these measurements
An angle describes rotation between directions.
The base reference used here is the radian. One gradian is 0.01570796327 base units; one turn is 6.283185307 base units.
Important distinctions
A full turn is 360 degrees or 2π radians. Signed angles are permitted.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
