Default Interpreting Sensor Sizes

When sensor size is 1/1.7", is this just a crazy fraction with a decimal,
which is to say 0.59"?

Is the the diagonal length across the sensor (like a tv set measurement)?

Then some manufactures say something like 23x15mm further confusing me.

How can I convert these numbers into something I can compare?

And lastly, if my first question is right, is there an appreciable difference between a 1/1.7" and 2/3" sensor (0.59 v. .67)?

Thanks

Take a look, under the General Discussion forum, at the thread about sensor size and crop factor. The first post shows a comparative graphic.

It's even crazier than that. From the Wikipedia article on Image sensor format:
