Query: Reply to Comment on "Global positioning system test of the local
  position invariance of Planck's constant"   We reply to a Comment [Berengut and Flambaum, Phys. Rev. Lett. 109, 068901
(2012), arXiv:1203.5592] on our recent Letter [Kentosh and Mohageg, Phys. Rev.
Lett. 108, 110801 (2012), arXiv:1203.0102]. The Comment objects to our work
partly because $h$ has dimensions and therefore measuring any variation of it
is meaningless. We reply that the relevance of dimensions in the study of
fundamental constants has been the subject of some debate. We also note that
our model differs from the one normally used to compare hydrogen masers and
cryogenic optical resonators. Ours is based on a different treatment of proper
length and energy to conform to general relativity. We also enclose in an
Appendix our transmittal to the editors of Physical Review Letters.
