replace lines in a file

I've got a file full of numbers, example:

Code:

cat test.file

60835287
0
51758036
40242437
0
32737144
0
24179513
0
4131489957

I want to replace those numbers

Code:

TMP2="/root/test.file"
for number in `cat $TMP2` ;do
     calc=$(awk -v a="$number" 'BEGIN{printf "%.2f\n GB",  a/1024/1024}')
     sed -i 's/$number/$calc/g' $TMP2
done

Code:

TMP2="/root/test.file"
for number in `cat $TMP2` ;do
     calc=$(awk -v a="$number" 'BEGIN{printf "%.2f\n GB",  a/1024/1024}')
     sed -e 's/$number/$calc/g' > test.txt
done

But it doesn't work at all, what is the problem? I'd guess it's something to do with the variables and sed, like it doesn't read them..

I've also tryd putting the sed command or variables into double quotes (sed -e "s/$number/$calc/g" > test.txt ) but that doesn't help either!
