About these measurements
An angle describes rotation between directions.
The base reference used here is the radian. One radian is 1 base units; one quadrant is 1.570796327 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.
