What is h-bar value?
The currently accepted value for ℏ is 1.054571817×10-34 J-s (according to the 2019 International Bureau of Weights and Measures). Planck’s constant is ubiquitous in quantum mechanics, where it relates energy to frequency and momentum to wavevector, in other words relating kinematic properties to wave properties.
Is HBAR H 2pi?
A modified form of Planck’s constant called h-bar (ℏ), or the reduced Planck’s constant, in which ℏ equals h divided by 2π, is the quantization of angular momentum. For example, the angular momentum of an electron bound to an atomic nucleus is quantized and can only be a multiple of h-bar.

What is h-bar 2?
In general , the spread in position is at least inversely proportional to the spread in momentum: (Delta x) (Delta p) >= hbar/2 (it turns out the exact minimum is hbar /2 if Delta x and Delta p are defined as the standard deviations from the mean). This is called the Heisenberg uncertainty relation.
