The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.

 Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS"). Other ways to donate

 OFFSET -33,1 COMMENTS From Raphie Frank, Dec 17 2012: (Start) There are at least five different methods of determining Planck's constant (h). Listed below are the best estimate CODATA values for each of these five methods as of December 2012. 6.6260657(88)*10^(-34) J*s - Faraday Constant method. 6.6260678(27)*10^(-34) J*s - Josephson Constant method. 6.62606889(23)*10^(-34) J*s - Watt Balance method. 6.6260724(57)*10^(-34) J*s - Magnetic resonance method. 6.6260745(19)*10^(-34) J*s - X-ray crystal density method. (End) The latest definition is that the Planck constant h is exactly 6.62607015*10^(-34) J*s, according to the ISO standard (effective on May 20th, 2019). h is one of the seven 1990 SI units, see the second BIPM link and A322415. - Ralf Steiner, Dec 17 2018 and Wolfdieter Lang, Feb 12 2019 REFERENCES H.
