About Angle Converter

Angle Converter switches between degrees, radians, gradians, arcminutes, arcseconds, and turns for maths, physics, and engineering work. Students searching "degrees to radians", "radians to degrees", or "angle converter" need accurate factors without memorising every constant.

Enter a value, choose From and To units, and read the result. A full turn is 360°, 2π radians, or 400 gradians - keep calculator mode (DEG/RAD) consistent when you use the result in a scientific calculator.

Trigonometric functions in programming libraries often expect radians. Convert deliberately before calling sin, cos, or tan in code.

Benefits of Angle Converter

Degrees and radians Core pair for school and code.
Gradians and turns Extra units for specialised fields.
Arcminute/arcsecond support Useful for precision and astronomy-style measures.
Instant From/To swap style flow Fast homework checks.

Frequently asked questions

How many radians in 180 degrees?

π radians (about 3.14159).

What is a gradian?

A unit where a right angle is 100 gradians and a full circle is 400.

Does my calculator use degrees or radians?

Check the DEG/RAD mode before evaluating trig functions.

What is a turn?

One full rotation - equal to 360 degrees.

Are arcseconds used in everyday maths?

More common in astronomy and high-precision measurement than in basic algebra.
