You need to add a conversion step (GB, MB, KB ...) as well as to remove superfluous comas since the dot stand for decimal separator.

Code:
awk -F";" 'tolower($0)!~/parent: line/{k=1024;m=k*k;g=k*m;for(i=10;i<=14;i++) {gsub(",",z,$i);split($i,a," ");s+=a[1]*(a[2]=="GB"?g:a[2]=="MB"?m:a[2]=="KB"?k:1)} print $0 FS "sum=" s/m "[MB]="s/g "[GB]"}' OFS=";" yourfile

Idented properly :

Code:
awk -F";" 'tolower($0)!~/parent: line/{
k=1024;m=k*k;g=k*m;
for(i=10;i<=14;i++) {
        gsub(",",z,$i);split($i,a," ")
        s+=a[1]*(a[2]=="GB"?g:a[2]=="MB"?m:a[2]=="KB"?k:1)
    }
print $0 FS "sum=" s/m "[MB]="s/g "[GB]"
}' OFS=";" yourfile

tolower

TOUPPER(3)						     Linux Programmer's Manual							TOUPPER(3)

NAME

       toupper, tolower - convert letter to upper or lower case

SYNOPSIS

       #include <ctype.h>

       int toupper(int c);
       int tolower(int c);

DESCRIPTION

       toupper() converts the letter c to upper case, if possible.

       tolower() converts the letter c to lower case, if possible.

       If c is not an unsigned char value, or EOF, the behavior of these functions is undefined.

RETURN VALUE

       The value returned is that of the converted letter, or c if the conversion was not possible.

CONFORMING TO

       C89, C99, 4.3BSD.

BUGS

       The  details  of  what constitutes an uppercase or lowercase letter depend on the current locale.  For example, the default "C" locale does
       not know about umlauts, so no conversion is done for them.

       In some non-English locales, there are lowercase letters with no corresponding uppercase equivalent; the German sharp s is one example.

SEE ALSO
