🎯 Degrees → Arcseconds
Express degrees as arcseconds for ultra-fine angular precision.
Vital for astronomy, surveying, and optical alignment where tiny angular differences matter.
0.25 degrees equals
900 arcseconds
Arcminutes: 15
How to Use This Calculator
Enter degrees
Type the angular measurement in decimal degrees.
Check arcseconds
The converter multiplies degrees by 3,600 to produce arcseconds.
Review arcminutes
Arcminutes provide an intermediate precision level between degrees and arcseconds.
Formula
1 degree = 60 arcminutes
1 arcminute = 60 arcseconds
Arcseconds = Degrees × 3,600
Arcminutes = Degrees × 60
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Arcseconds are the smallest common unit in the sexagesimal angle system, essential when measuring celestial coordinates or adjusting precise optical equipment. This calculator handles the necessary multiplication so you can focus on the measurements themselves.
It supports fractional degrees and maintains high precision, making it suitable for professional surveying and astronomy workflows.
Combine it with the degrees-to-minutes and degrees-to-radians tools for a comprehensive angular conversion toolkit.
Frequently Asked Questions
Is the conversion exact?
Yes. Arcseconds are defined as 1/3,600 of a degree, so the conversion is a simple multiplication.
Can it handle negative angles?
Yes. Negative values preserve direction, useful in coordinate systems with signed declinations or bearings.
How many decimal places are shown?
The display adapts to the unit’s preferred precision. Arcseconds show without decimals by default but can be configured in code.
What if I need milliarcseconds?
Multiply the arcseconds result by 1,000 for milliarcseconds, or extend the converter to include that unit.
