How to convert arcseconds to gradians
A full turn is 2π radians, 360 degrees, or 400 gradians. Decimal degrees are not degrees-minutes-seconds notation. Angular minutes and seconds are not time units.
Use x for the value in ″, b for the intermediate value in rad, and y for the result in gon.
gon = ″ × 0.00000484813681109536 ÷ 0.015707963267948967
Worked examples
10 ″ ≈ 0.00308641975309 gon
Step 1: (10 × 0.0000048481368111) ≈ 0.000048481368111 rad.
Step 2: 0.000048481368111 ÷ 0.0157079632679 ≈ 0.00308641975309 gon.20 ″ ≈ 0.00617283950617 gon
Step 1: (20 × 0.0000048481368111) ≈ 0.0000969627362219 rad.
Step 2: 0.0000969627362219 ÷ 0.0157079632679 ≈ 0.00617283950617 gon.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Arcseconds
Arcseconds (″) measures angle under the conventions above. The base value in rad is (x × 0.0000048481368111), where x is the numerical value in ″. Factors shown here are rounded for display; calculations use the stored factor.
About Gradians
Gradians (gon) measures angle under the conventions above. The base value in rad is (x × 0.0157079632679), where x is the numerical value in gon. Factors shown here are rounded for display; calculations use the stored factor.
