Unit conversion
Angle Converter
Convert angles between degrees, radians, and gradians using π-based factors, with a one-radian to degrees example and signed angle support.
How it works
180 deg = π rad = 200 grad; 1 deg = π/180 rad; 1 grad = π/200 rad
1 rad = 57.2958 deg (rounded).
Convert through the base unit: result = value × source factor / target factor. Factors above specify each unit in the base unit. Results are rounded only for display.
FAQ
What is a gradian?
A gradian (grad or gon) divides a right angle into 100 parts. A full turn is 400 grad.
Are angles wrapped to a single turn?
No. The converter preserves the full signed angle, including values larger than one revolution.
Can I convert negative angles?
Yes. The sign is preserved when converting between degrees, radians, and gradians.
