Customise returned data format on view tab

Hi
With the fieldname__renderCell() function I have been able to add for example "GB" to the output for HDD size storage on the list page. Ie. I have 250 stored in the database but it outputs it as "250 GB" in the list table.
How can I do this on the view page specific to the record though?
Thanks!
