What is the base unit of Plancks constant?

Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.
