    If you are using a wire made out of (say) iron the formula would be

    R = k * L / (pi * r^2)

    pi r^2 represents the cross sectional area.

    L is the length of the wire.

    k is the resistance constant for that material.

    So, resistance is measured as

    k which depends on the material. It is different for all materials. Copper Silver and Gold for example, all have different k values.

    L is the length of the material

    pi * r^2 is the area of a thin slice of this material.
