About Degree and Arcsecond

Detailed information about both units of measurement.

ANGULAR UNIT

Degree

°
Definition
The most common angular unit. A full circle is divided into 360 equal parts called degrees.
SI / Standard Information
Not an SI unit but widely used. The 360-degree system originates from ancient Babylonian astronomy and their base-60 number system.
Approximate Comparison
One degree is about the width of a little finger held at arm's length.
Practical Applications
  • Navigation and GPS coordinates
  • Engineering and construction angles
  • Geometry and mathematics education
  • Compass and direction measurement
Real-World Examples
  • A right angle is 90 degrees
  • The Earth's axis is tilted at 23.5 degrees
  • A triangle's interior angles sum to 180 degrees
ANGULAR UNIT

Arcsecond

"
Definition
One-sixtieth of an arcminute or 1/3,600 of a degree. Used in precision astronomy.
SI / Standard Information
Also called a second of arc. 1 arcsecond = 1/3600 degree. The parsec (parallax arcsecond) is derived from this unit.
Approximate Comparison
One arcsecond is about the apparent size of a US quarter at a distance of 4 km.
Practical Applications
  • Professional astronomical measurements
  • Space telescope resolution (Hubble, JWST)
  • Geodetic surveying
  • Stellar parallax calculation
Real-World Examples
  • The Hubble Space Telescope has 0.05 arcsecond resolution
  • The largest apparent planet (Venus) is about 1 arcminute
  • A human hair at 1 km is about 1 arcsecond wide
