The linear momentum must have a dimension does it not?in what kind of units is it measured?

Was there ever a dimensional analysis madeon the foton units?

The momentum of a photon is given by the following equation:
p = hf/c
where p is the momentum, h is planck's constant, f is the frequency of the photon, and c is the speed of light.
Edit:
The unit of momentum of a photon is the same as standard momentum, namely a mass*velocity. For the equation above the units of p are kilogram*meter/second.

The momentum of a photon is Planck's constant divided by the wavelength of the light.
