Peter Luschny: I think your point of view is fine! Publish recognized values but do not play the judge about conventions in communities which arose in long and difficult discussions; and refrain from chasing the latest craze just because they have recently received publicity.

DATA

1, 6, 1, 6, 2, 2, 9

COMMENTS

This value is subject to further revision in the future as it is dependent upon the value of G, the gravitational constant, and h, Planck's constant.

This value keeps changing, and so this sequence keeps changing. The previous version from 2012 was 1, 6, 1, 6, 1, 9, 9. - N. J. A. Sloane, Aug 18 2017

As a result of the Mohr et al. paper many other sequences in the OEIS will also need updating. - L. Edson Jeffery, Aug 18 2017

EXAMPLE

Planck length = 1.616199(97) 6162... * 10^(-35) meters.

Andrey Zabolotskiy: The current CODATA value is 1.616255(18), so I, as usual, dropped the digits that aren't stable within +-1 std error variation. Also, I've removed the comments because similar comments could be added to dozens of other OEIS sequences but we never do so.

Andrey Zabolotskiy: I especially hope on Peter Luschny's support on this and other my today's edits.
