Enter the energy and the frequency into the Calculator. The calculator will evaluate the Planck’s Constant. 

Planck’s Constant Formula

h = E / f


  • h is the Planck’s Constant (J-s)
  • E (J) is the energy
  • f (hz) is the frequency

To calculate Planck’s Constant, divide the energy by the frequency.

How to Calculate Planck’s Constant?

The following steps outline how to calculate the Planck’s Constant.

  1. First, determine the energy. 
  2. Next, determine the frequency. 
  3. Next, gather the formula from above = h = E / f.
  4. Finally, calculate the Planck’s Constant.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
