Formulas for angle conversion


\(\displaystyle 1 \space degree = 60\space arcminutes =3600\space arcseconds \)


\(\displaystyle degree = radians \frac{180}{π} = gradient\frac{90}{100} \)


\(\displaystyle radians = degree\frac{π}{180} = gradient\frac{π}{200} \)


\(\displaystyle mil = Grad \frac{3200}{180} = gradient ·16 \)


Convert decimal degrees to degrees, minutes and seconds


\(\displaystyle deg_{dec} = 45.515 \)


\(\displaystyle deg = int(deg_{dec}) \)
\(\displaystyle = int(45.515)= 45 \)

\(\displaystyle min_{dec} = (deg_{dec} - deg) ·60 \)
\(\displaystyle = (45.515 -45)·60= 30.9 \)

\(\displaystyle min=int(min_{dec})\)
\(\displaystyle = int(30.9) = 30 \)

\(\displaystyle sec = (min_{dec} - min) · 60\)
\(\displaystyle = (30.9-30)·60= 54 \)

Result = 45°   30'   54''
