Illustration of a pizza with a slice cut
138,383 second (38.4 degrees) is comparable to the angle of a pizza slice cut from a whole pie.

Did you know? Pizza slice (8 slices) is 45°.

A pizza cut into 8 equal slices gives 45° per slice. Six slices = 60°; 12 slices = 30°.

How to Convert Second to Radian

About these units

Second: An arcsecond (second of arc) is 1/60 of an arcminute.It is common in astronomy, surveying, astrometry, and precision optics for high-precision angles.

Radian: The radian (rad) is the SI derived unit of plane angle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius.Although mathematically dimensionless, th...
