Angle Converter & Trig FAQ
What formulas does the angle converter & trig use?
rad = deg × π / 180; grad = deg × 10 / 9; 1 turn = 360° = 2π rad.
How many degrees is one radian?
One radian is 180/π ≈ 57.2958°, and a full turn is 2π radians (360°).
Can I use different units?
This tool works in degrees, radians, gradians or turns; pick the unit of your input from the list.
Is this angle converter & trig free and private?
Yes. It is free with no sign-up, and calculations happen on your device, so your numbers are never sent to a server.
