Use Cases

Optics and Imaging

In optics, lens specifications and image resolution are sometimes given in degrees. Convert these to arcseconds to compare with camera sensor pixel scales or to calculate field of view details.

Example: A lens with a 1.2-degree field of view equals 4320 arcseconds.

Frequently Asked Questions

How many arcseconds are in one degree?
There are 3600 arcseconds in one degree. This is because each degree is divided into 60 arcminutes, and each arcminute is divided into 60 arcseconds (60 × 60 = 3600).
Can I convert arcseconds to degrees with this calculator?
Yes, the calculator allows you to select the 'Convert from' and 'Convert to' units. Choose 'ARCSECONDS' as the 'Convert from' unit and 'DEGREES' as the 'Convert to' unit to perform the reverse conversion.
What is the formula used for the conversion?
To convert degrees to arcseconds, multiply the number of degrees by 3600. For example, 2 degrees equals 7200 arcseconds. The calculator applies this formula automatically.

Tips & Common Mistakes

Tips

  • Remember that 1 degree = 60 arcminutes = 3600 arcseconds. Keep this factor in mind for quick mental conversions.
  • For very small angles, arcseconds provide a more precise unit than degrees. Use this converter to avoid rounding errors.
  • Double-check your input: ensure you have selected the correct 'Convert from' and 'Convert to' units to avoid reversed conversions.
  • If you need to convert multiple values, use the calculator repeatedly or note that the conversion factor is constant.

Common Mistakes to Avoid

  • Forgetting that there are 3600 arcseconds in a degree, not 60. This is a common error because arcminutes are 60 per degree.
  • Selecting the wrong direction for conversion, e.g., choosing 'ARCSECONDS' as 'Convert from' when you intended to convert from degrees.
  • Misplacing decimal points when entering values, especially when dealing with fractional degrees.
