I How to confirm unit of electron mobility as m^2/(V*S)?

    Hello.

    Electron mobility in plasma is μ = q/m⋅ν, where q, m and ν are charge and mass of electron and electron collisional frequency. (https://en.wikipedia.org/wiki/Electrical_mobility)

    And unit of the mobility is m2/V⋅S (https://en.wikipedia.org/wiki/Electron_mobility)

    According to the formula, dimension of the mobility is firstly C⋅s/kg. But I don't know how to reach m2/V⋅S from from this.

    Could you please help me to derive this?

    Thank to read this!

    I'm sorry but I found the answer immediately.

    V = kg⋅m2⋅s-3⋅A-1 (https://en.wikipedia.org/wiki/Volt)

    Substituting V into m2/V⋅s gives C⋅s/kg.

    Problem is solved:)
