Dear SeqFans,

A248424 gives the decimal expansion of the value of 1 Parsec in meters.
According to Wikipedia, (https://en.wikipedia.org/wiki/Parsec), since 2005,
1 Parsec is defined to be exactly (648000 / Pi) astronomical units (AU).
The AU itself is defined to be exactly 149597870700 meters. With this, I get
1 Parsec = (648000/Pi) * 149597870700 =
30856775814913672.789139379577964716107319211604092.... meters.

Why does this value differ from the value given in A248424? Why does
A248424 give a different definition (see for example the comment by M. F.
Hasler)? Who is correct?

Best regards
Felix Fröhlich
