focal length multiplier Sony PC 107 and x0.6

[j3zz 0]

Ok so I have just started reading up on all sorts of technical stuff.

From the sony website.
f (35mm conversion): Camera mode (mm) 43-430
f (Focal Distance) (mm) 2.3-23

Would it be correct to assume that the focal length multiler for this camera is ~18.7

Also if you then screw on a x0.6 wide angle do you get an effective focal length of 25mm on a 35mm conversion.

If so how does that work as I though focal length was based on the location of the lens.

I am very new to camera stuff so just wanting to glean all the info I can from those more knowledgeable than myself.
