Pantone Coated to RGB & Hex values: which app to trust?

[Blue Velvet]

Over the next few hours, I've got to take some PMS solid coated swatches and convert them to RGB and Hex values; something I never usually have to do, being a print designer. I don't have any guides here at home tonight so have to do this electronically.

For the same chip, I'm getting different RGB and Hex results from Illustrator, Photoshop and Art Directors Toolkit which isn't helping matters at all.

And also different to ones presented here.

Advice?

Sorry to double post, but given the deadline, I did a little more digging and found this from David Blatner, who I rate tremendously highly:

I have to agree, Tim: Using a swatch book is always a good idea. Also, just because Photoshop thinks it’s a good match doesn’t mean it’s the best match. In my experience, the Pantone it picks is far from the original color and I can better replicate it by eye — if I’m willing to accept a more desaturated color, or a darker color, or any of the other variables that come into play.
That said, Claudia’s tip gets me much closer, especially when working fast!
Wa: I had forgotten about Art Director’s Toolkit. I haven’t played with it for a long time, and it’s no longer bundled on my Mac. Too bad. Looks like a great program and has a much better color matching system.

Case closed for me for now, for this job. I've got to get on with things... I'd still be interested in hearing other's opinions, though.
