There is no correspondence of points to pixels, since the number of pixels used for a particular resolution will vary - considerably - by device.
If you are designing a project where the end product is to be printed, use a print-centric application (Illustrator, InDesign) and set your measurements in points. But set your dpi after you know the resolution of the output device and if you need its full resolution. (If you're printing flyers for people to hold in their hands, you need higher resolution. If you're printing banners to be viewed across the freeway, you can use lower resolution.)
If you are designing a project where the end product is to be viewed on screen (such as a Web page), then you need to design in pixels, not points. The output devices (monitors) produce colored dots in pixels. Pixels as points have no common reference point across all devices, so there can be no common conversion. Read these two articles and encourage your client to, as well:

Many thanks for the information.
Unfortunately due to the excessive price of the full CS4 suite in the UK, I
could only afford to purchase the Web suite, which does not have either of
these programs. I will look through my earlier programs and see if they are
capable of doing the job.
As the end result has to be print and screen compatible, then I will have to
produce two versions.
Then you might look at Inkscape, which is free, and can produce vector graphics you can use in print documents as well as in Fireworks.
Fireworks is not the best application to use to design a vector logo in. FW is intended for screen graphics, it is not a general drawing/illustration tool.
I agree, but I use what I have. Looks like so many people have read your
post that the Inkscape site is swamped. Will try a download later. Thanks a
