COMMENTS
Before its redefinition in 2015, a parsec was defined as the distance at which one astronomical unit subtends an angle of one arcsecond, which yielded the slightly different value of 1 au/tan(Pi/(180*3600)), cf. A248424.
FORMULA
1 pc = 1 au * (3600*180 / Pi) = 30 856 775 814 913 672.789... m, since 1 au = 149597870700 m.
Equals A217572 * A163103.
