The symbol h is used to express the value of the Planck constant in J⋅s/cycleLet's do some unit analysis.

The time unit as numerator there, indicates that the value is an accumulated quantity over time, which is second. It's similar to mAh in battery capacity, or kWh in energy consumption.

The cycle as denominator means that the value is the rate of a quantity, which is per cycle.

When a quantity of radiation has value of 6.62607004 x 10

^{-34}J. s/cycle, it means that

6.62607004 x 10

^{-34}Joule of energy is transfered in 1 second interval for each cycle.

If the frequency is 1 Hz, then there is 1 cycle in a second. Thus, in 1 second interval the energy transfered is 6.62607004 x 10

^{-34}Joule.

If the frequency is 1 THz, there are 1 trillion cycles in a second. So the energy transfer accumulated in 1 second is 6.62607004 x 10

^{-22}Joule.
