  1. It's in KB. To see in human-readable format try df -h
  2. find /path/ -type f -size +1000M

In your closed (duplicate) post you mention that you do not have "root" access. You need "root" access and good local knowledge to clean up /var . Also "find" will not see much of the system if you are not "root".

What Operating System and version is this?
