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.

LINKS

Table of n, a(n) for n=17..111.

FORMULA

1 pc = 1 au * (3600*180 / Pi) = 30 856 775 814 913 672.789... m, since 1 au = 149597870700 m.

Equals A217572 * A163103.

PROG

(PARI)  149597870700*648000/Pi

CROSSREFS

Cf. A248424 (pre-2015 definition), A163103, A217572, A248645.

Sequence in context: A223854 A333567 A248424 * A275975 A201665 A137204
