Still confused - String width to point size

Several of the PDFont methods have the explanation:

" The width is in 1000 unit of text space, ie 333 or 777" for string width
and so on.

I am not really clear what this means. How can I relate to points? Thanks
for any help.

Cheers, srini

Copied from th PDF-reference 1.7:

"The glyph widths are measured in units in which 1000 units corresponds to 1 
unit in text space."

e.g.

font character width = 777
fontsize = 12pt
points in text space = 777/1000*12 = 9,324
