method convertSize documentation in bbn\Str
Converts size from one unit to another.
Example
var_dump(\bbn\Str::convertSize(1, 'GB', 'B'));
// (string) "1073741824B"
var_dump(\bbn\Str::convertSize(1, 'TB', 'GB'));
// (string) "1024GB"
var_dump(\bbn\Str::convertSize(500000, 'MB', 'TB', 6));
// (string) "0.47684TB"

}

}

// If destination unit is smaller than the original then reverse the units array
