Collision frequency unit conversion

  1. Dec 15, 2014 #1
    hi all

    I have a question about unit for collision frequency. The unit is collision per second and is it same with hertz?

    Thanks

    To elaborate: a "collision" is not a physical quantity, so it doesn't have a unit. Which leaves you with frequency (Hertz), which is actually a kind of artificial unit (derived), since it is any event per second.

    They have the same dimensions but aren't necessarily the same unit. For example the becquerel .the unit of radioactive decays (1Bq is one decay per second), has the same dimensions as the hertz(1Hz is one cycle per second), but is not the same unit.

    Yes, sorry, Bq and Hz are different units, same dimension (different name for the same concept).
