deg to arcsec calculator

Angles are measured in degrees, arcminutes, arcseconds, radians, and gradians. While degrees are common in everyday applications, arcseconds are vital for astronomy, surveying, navigation, and precision engineering, where very small angles must be measured accurately.

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 crucial in astronomy, geodesy, and precision engineering because they allow very fine measurements of angles.

Degrees to Arcseconds 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″
