BinaryUnits= unit1; unit2;...
Binary units will get binary prefixes in front of the 'B' for byte or 'b' for bit. The possible units are listed in units.ini.
Use the UseSIUnits settings to force eZ publish to use SI prefixes instead of the standard OSI approved prefixes.
The configuration file units.ini allows you to alter the prefixes.
