The fun bit is that Pantones are designed for reflective/absorbative media (eg
ink
on paper). Web colours are direct light being produced by displays.

Also, you won't even get perfect matches between Pantone spot colours and CMYK
process colours, let alone a completely different colourspace of RGB.

However, here's how to get close:
1) Get an accurate patch of colour in Photoshop (fill it with a Pantone-accurate
swatch)
   in CMYK mode
2) Convert document to RGB
3) Take a sample in the patch
4) Note the Red, Green & Blue values of this colour (don't bother with HSB or
anything else)
5) Each will be a value from 0-255, which converts into a 2 digit hexadecimal
value (remember
   school maths - divide by 16 to get the 1st digit. If it's over 10, then go on
from 9 to A, B, C...F.
   Then do the same 1-F thing for the remainder)

Or, if you care about being web-safe, it's even easier:
Web safe colours have values for each of the 3 colours from the following list:

Hex:  Dec:
00      0
33     51
66    102
99    153
CC   204
FF   255

(or multiples of 33 (hex) and 51 (decimal))

Easy when you know how.

Cheers
Martin
