How it scales

1 turn (360°) in other units

The ratio at a glance

Degrees, radians, and gradians — the key angle units

The degree (°) divides the full circle into 360 parts and is the everyday unit in geometry and navigation. The radian (rad) is the standard mathematical unit: 180° = π rad, so 1 rad ≈ 57.2958°. The gradian (gon) divides the circle into 400 parts, so one full turn is 400 grad = 360° and 1 grad = 0.9° — common in surveying because a right angle is exactly 100 grad.

For very small angles the degree is subdivided further: 1° = 60 arcminutes (′) and 1 arcminute = 60 arcseconds (″), so 1° = 3,600 arcseconds — used in astronomy and navigation. A turn describes one full circle (360°). For more unit pairs, use our angle conversion hub.

Frequently asked questions

How many turns are in 1 rad?

1 rad equals 0.159 turns.

How many turns are in 2 rad?

2 rad equal 0.318 turns.

How do I convert rad to turns?

Divide the angle in rad by 6.28 to get turns.

How are degrees and radians related?

A full circle spans 2π radians or 360°, so 180° = π rad. From this: 1 rad = 180/π ≈ 57.2958° and 1° = π/180 ≈ 0.0175 rad. The factor π appears because the radian is defined from the circle's arc length.

What are these angle units used for?

Degrees (°) are the everyday unit in geometry and navigation. Radians (rad) are the standard mathematical unit, especially in trigonometry and physics. Gradians (gon) are used in surveying, while arcminutes and arcseconds express very small angles in astronomy and navigation. A turn describes one full circle (360°).
