# Full Rotation

### A full rotation is 360 degrees

This is a "full rotation"
or "revolution"
or "complete turn"
or "full circle"

It means turning around until you point in the same direction again.

Note: RPM means "Revolutions Per Minute"
(how many full rotations every minute)

Other ways of saying it:

• "Doing a 360" means spinning around completely once (spinning around twice is a "720").
• "I gave the wheel one complete turn looking for holes"
• "It completed one cycle", meaning it went around exactly once.
• "It was spinning at 200 revolutions per minute" (but people usually say "RPM" instead of "revolutions per minute").
• "She went full circle on liking carrots". So maybe she originally liked carrots, then hated them, now she likes them again.

This image of a protractor shows that a full rotation is 360°

And Half a rotation is 180°, called a Straight Angle

And Quarter of a rotation is 90°, called a Right Angle

And a full rotation is also equal to 2π Radians, so here are some equivalent values:

 Rotations Radians Degrees ¼ π/2 90° ½ π 180° 1 2π 360° 1½ 3π 540° 2 4π 720°
