degree to arcsecond calculator

Angles can be measured in degrees, arcminutes, arcseconds, radians, and gradians. While degrees are common in everyday use, arcseconds are essential for astronomy, surveying, navigation, and precision engineering, where very fine angle measurements are required.

What is a Degree?

A degree (°) is a standard unit of angle measurement:

• 1 full circle = 360°
• Degrees are widely used in geometry, navigation, construction, and astronomy.

What is an Arcsecond?

An arcsecond (″) is a subdivision of a degree:

• 1 degree = 60 arcminutes (′)
• 1 arcminute = 60 arcseconds (″)
• Therefore: 1 degree = 3600 arcseconds

Arcseconds are commonly used in astronomy, geodesy, and precision engineering, allowing for highly accurate angular measurements.

Degree to Arcsecond Conversion Formula

To convert degrees into arcseconds, use the formula:

Formula:
arcseconds = degrees × 3600

Example Conversions

1. Convert 1° to arcseconds
   • arcseconds = 1 × 3600 = 3600″
2. Convert 0.5° to arcseconds
   • arcseconds = 0.5 × 3600 = 1800″
3. Convert 2° to arcseconds
   • arcseconds = 2 × 3600 = 7200″
4. Convert 45° to arcseconds
   • arcseconds = 45 × 3600 = 162,000″
5. Convert 360° to arcseconds
   • arcseconds = 360 × 3600 = 1,296,000″
