Dear student 
Planck's constant, symbolized h, relates the energy in one quantum (photon) of electromagnetic radiation to the frequency of that radiation. In the International System of units (SI), the constant is equal to approximately 6.626176 x 10-34 joule-seconds.
Its  relates the energy carried by a photon to its frequency. A photon's energy is equal to its frequency multiplied by the Planck constant.
E = h* v
Dimention of Planks constant = h = ML^2 T^-1
Hope this helps 
Good luck
