The constant of proportionality relating the energy of a photon to its frequency; approximately 6.626 x 10^-34 joule-second WordNet 3.0 & Open English WordNet
The Planck constant, or Planck's constant, denoted by h {\textstyle h}, is a fundamental physical constant of foundational importance in quantum mechanics: a photon's energy is equal to its frequency multiplied by the Planck constant, and the wavelength of a matter wave equals the Planck constant divided by the associated particle momentum. Wikipedia

The constant of proportionality (symbol h), relating the energy and frequency of a photon (6.626 × 10−34 joule-seconds); also related to the indeterminacy limit in the Heisenberg uncertainty principle; the quantum of action. Wiktionary
