[ubuntu-za] Nautilus shows wrong size

[Wikus]

Afternoon all ,

I have picked up a little niggle in my Nautilus. It shows the "wrong" size.
It shows the "raw" size and not the correct "converted" size in MB or GB if
you know what I mean. The link I included has a screenshot to show what 
I mean.
That iso's size is actually 695MB , but my Nautilus shows the raw 728MB 
which is wrong.
I checked and saw that it is only in Nautilus that it shows wrong. In 
terminal the size shows
correctly as 695MB. I also saw that it is on all files like that , not 
only that 1 file.

How can I fix it to show the correct MB and GB size in Nautilus please ?
