ScaleHint in GetCapabilities resquest

[Jacolin Yves]

Hi list,

After a GetCapabilities resquest on a mapserver server, I find this line 
inside my xml file:
<ScaleHint min="9.97805696859274" max="249.451424214819" />

In my mapfile, I defined min et max scale values with:
   MINSCALE 20000
   MAXSCALE 500000

How can I convert the scaleHint value to the mapfile value? In other words, 
what does scaleHint values means?

Thanks,

Y.
