Descompose memory result

[guif]

I use this command to give my free memory in my system: free | grep Mem | awk '{ print $4 }'

And, I would like to know what's the arithmetical math to descompose this result into Gb, Mb and Kbytes.
For example, If I have 1048577Kbyes

1048577 / 1024 = 1024,0009 Mb
1024,0009 / 1024 = 1 Gb

my result: 1GB, 1Mb, 0Kbytes.

I would like to make this with and script.

Help me please!

Your question is a continuation of this thread.

In that thread, we gave you the tools. We're not likely to write the script for you. If you know nothing about writing bash scripts, then scroogle the following search terms:

Good luck! :)

yes but it's different.
In my first post i put the total memory in GB, Mb and Kbytes,

now i would like to make an operation (i don't know to make it!)

So now it's time for you to learn about bash and bash scripting.
