When to use it
Converts radians to degrees. Trig functions return radians, so this is how you read the answer.
The shape of it
- Syntax
=DEGREES(angle)
Worked examples
Half a turn
=DEGREES(PI()) → 180
Pi radians is half a turn.
One radian
=DEGREES(1) → 57.29577951
One radian.
Angle from coordinates
=DEGREES(ATAN2(1,1)) → 45
The angle of the line from the origin to (1,1).
Worth knowing
- Bearings from coordinates: =MOD(DEGREES(ATAN2(dy,dx)),360).
- RADIANS goes the other way.
- DEGREES(x) = x*180/PI().
Where it goes wrong
- Feeding degrees into SIN without converting gives nonsense with no error.
- Results can carry tiny floating-point residues; ROUND for display.
