DIMENSIONAL ANALYSIS EQUATION CALCULATOR
    Too many times losing time with dimension calculations ? I found a cheap way to solve the huge amount of System International physical values such as kilogram, meter, ampere, second.
    Below a simple code to be inserted in Mathematica. Below I added an example for the demo.

    V = kg*m^2*s^-3*A^-1; (*Voltage in V*)
    R = kg*m^2*s^-3*A^-2; (*Resistance in ohm*)
    L = kg*m^2*s^-2*A^-2; (*Inductance in henry*)
    Ca = kg^-1*m^-2*s^4*A^2;(*Capacitance in faraday*)
    Nw = kg*m*s^-2; (*Force in newton*)
    Joule = kg*m^2*s^-2; (*Energy in joule*)
    Po = kg*m^2*s^-3; (*Power in watt*)
    M = kg*m*s^-1; (*Momentum*)
    B = kg*s^-2*A^-1; (*Magnetic induction in tesla*)
    Ef = kg*m*s^-3*A^-1; (*Electric field*)
    Pr = kg*m^-1*s^-2; (*Pressure in pa*)
    Mu = kg*m*s^-2*A^-2; (*Vacum permeability*)
    Er = kg^-1*m^-3*s^4*A^2;(*Vacum permittivity*)
    h = kg*m^2*s^-1; (*Planck constant*)
    k = kg*m^2*s^-2*K^-1; (*Boltzmann constant*)
    Gravi = kg^-1*m^3*s^-2; (*Gravitat. cst*)
    Speed = m*s^-1; (*any speeds: light, sound, etc*)
    Coulomb = s*A; (*charges in Coulomb*)
    eV = Joule;

    Example with the current density J and terms on the right of equal sign:
    Fowler-Nordheim
    As a result we exactly obtain the current density dimension
