Angles are widely used in mathematics, astronomy, surveying, navigation, and engineering. While degrees are a standard unit, arcseconds (symbol: ″) allow for extremely precise measurements of small angles.

Manual conversion from arcseconds to degrees can be tedious, especially in astronomy and surveying. Our Arcsecond to Degree Calculator provides instant, accurate conversions, making it an essential tool for students, professionals, and researchers requiring precise angular measurements.

What is an Arcsecond?

An arcsecond is a subdivision of a degree, allowing for high-precision measurements.

• 1 degree = 60 arcminutes (′)
• 1 arcminute = 60 arcseconds (″)
• Therefore, 1 degree = 3,600 arcseconds

Arcseconds are extensively used in astronomy, surveying, cartography, and navigation to measure extremely small angles.

What is a Degree?

A degree divides a full circle into 360 equal parts.

• 1 full circle = 360 degrees
• 90° = right angle
• 180° = straight angle

Degrees are the most commonly used unit for general mathematics, navigation, geometry, and engineering applications.

Formula for Conversion

The formula to convert arcseconds to degrees is:

Degree = Arcsecond ÷ 3,600

Examples:

1. Convert 3,600″ to degrees:
   3,600 ÷ 3,600 = 1°
2. Convert 7,200″ to degrees:
   7,200 ÷ 3,600 = 2°
3. Convert 1,350″ to degrees:
   1,350 ÷ 3,600 = 0.375°
