The Planck constant has the same dimensions as action and as angular momentum. The Planck constant is fixed at $${\displaystyle h}$$ = 6.62607015×10 J⋅Hz as part of the definition of the SI units. Alternatively, if the radian were considered a See more
Many equations in quantum physics are customarily written using the reduced Planck constant, equal to $${\textstyle {\frac {h}{2\pi }}}$$ and denoted $${\textstyle \hbar }$$ (pronounced h-bar ).
