Summary
Convert angle values from degrees to arcseconds with the step-by-step formula.
How it works
- Enter an angle in decimal degrees (e.g. 1.5) or degrees, arcminutes, and arcseconds separately.
- The tool multiplies decimal degrees by 3,600 to get total arcseconds.
- For DMS input it first converts to decimal degrees: DD + MM/60 + SS/3600.
- The result is displayed with the full formula and each arithmetic step.
- Copy the result with one click for use in other applications.
Use cases
- Astronomy: express telescope resolution or celestial coordinates in arcseconds.
- Geodesy and surveying: convert field angle readings to arcseconds for precision calculations.
- Optics: compute angular separation or beam divergence in arcseconds.
- Navigation: break down course bearings into finer arc-second units.
- Education: verify angle-unit conversions in physics or earth-science coursework.
- GIS: prepare coordinate offsets that expect arcsecond values.
