Planck Constant Formula
Its value can be easily calculated by putting values in the Planck-Einstein relation for the Photoelectric effect energy:
E = ℎf
Where E is the energy of the light, and f is the known frequency of the light.
Unit of Planck Constant
Planck’s constant is a very small value can be written in two formats:
Planck Constant = 6.62607015 × 10−34 Joule seconds
Here, 10-34 is a very small value, which is 1 in its 34th digit.
Planck Constant = 4.135667696 × 10−15 eV seconds
Here, 10-15 is a slightly larger but equivalently smaller quantity, which is 1 in its 15th digit.

Dimension of Planck Constant is [ML2T-1]
Planck’s Constant
Planck’s Constant is one of the smallest constants used in physics. It is a fundamental constant in quantum mechanics which relates the energy of a photon to its frequency. Planck constant stands as one of the most elegant and pivotal values in the realm of physics, where constants shape the very essence of this physical world.
Further in this article, we will learn about its definition, who Max Planck was, explore methods for calculating its value in various units, its formula, dimension, and unit. We will look into what’s a Reduced Planck Constant and discuss the application of Planck’s constant across various scientific disciplines.
