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

## Planck’s Constant Formula

h = E / f

Variables:

- 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.

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