$units = explode(' ','B Kb Mb Gb Tb');

Hi there,

the correct abbrevations for memory sizes are as following:

• kilobyte: KB
• megabyte: MB
• gigabyte: GB
• petabyte: PB

The units in latest version (2.1.0) are wrong and describe the "bit sizes". For example "Mb" stands for "megabit", that is only one eight of a megabyte.

Best regards from Germany! :)
