How many arcseconds are in a degree?

1 ° = 3600 ″. To convert any amount, multiply by 3600.

How do you convert degrees to arcseconds?

Multiply the number of degrees by 3600 to get arcseconds. The formula is shown in the "How it's calculated" section above.

Where does the conversion factor come from?

It's a published international standard. Most are defined exactly by international agreement (e.g. 1 inch = 25.4 mm exactly, 1 lb = 0.45359237 kg exactly). Source citations are listed under the formula above.

How it's calculated

Convert degrees to arcseconds— the formula

Degrees convert to arcseconds by multiplying by the published conversion factor. The factor below is exact to the precision shown, sourced from the citation under the formula.

″ = ° × 3600

° = ″ × 0.000278

Radian: SI coherent derived unit for plane angle (BIPM). 1 full turn = 2π rad = 360° = 400 gon = 1 rev. 1° = 60 arcminutes = 3600 arcseconds (exact, by definition).
