H in joules

The Planck constant, or Planck's constant, is a fundamental physical constant of foundational importance in quantum mechanics. The constant gives the relationship between the energy of a photon and its frequency, and by the mass-energy equivalence, the relationship between mass and frequency. Specifically, a photon's energy is equal to its frequency multiplied by the Planck constant. The constant is generally denoted by . The reduced Planck constant, or Dirac constant… WebSince one watt-hour is equal to 3,600 joules, you can use this simple formula to convert: joules = watt-hours × 3,600 The energy in joules is equal to the watt-hours multiplied by 3,600. For example, here's how to convert 5 watt-hours to joules using the formula above. 5 Wh = (5 × 3,600) = 18,000 J How Many Joules Are in a Watt-Hour?
