how can we convert this java to find from bytes - kb,mb,gb (if theres another way im ok with it)

can someone please tell me in how to convert bytes to kb,mb,gb from any bytes number

id like the format of

4 Bytes
4.6 KB
4.6 MB
4.6 GB

that type of output bare in mind it would only be one of them

below is the code i found for java if that helps any

aka Pern
public String getFileSize(long fsize){
     //Set things up
     DecimalFormat   df         = new DecimalFormat("0.00");
     String              sizeType   = new String();
     String          returnSize = new String();
     //Calculate file sizes
      long fsize_kb   = fsize / 1024;
     long fsize_mb   = fsize / 1024 / 1024;
     long fsize_gb   = fsize / 1024 / 1024 / 1024;
      //Pick the right size i.e KB, MB or GB
      if(fsize_kb < 1500 ){
          returnSize = df.format(fsize_kb);
          sizeType = "KB";
      if(fsize_mb >= 1 && fsize_mb < 1000){
            returnSize = df.format(fsize_mb);
          sizeType = "MB";
       if(fsize_gb >=1){
            returnSize = df.format(fsize_gb);
          sizeType = "GB";
        //Return the size of the file with the right units....
       return(returnSize + sizeType);

im getting output like N2 KB

for a value of 3638

shouldnt it be around 3.4k or someplace around there??
really confused

11603 is converting to 2 KB as well it seams this dont work...

it should at least be 11k

go figure
here is a conversion for that java code you gave, it seems to work well:

    Private Function getFileSize(ByVal fsize As Double) As String
        'Set things up
        Dim sizeType, returnSize As String
        'Calculate file sizes
        Dim fsize_kb, fsize_mb, fsize_gb As Double
        fsize_kb = fsize / 1024
        fsize_mb = fsize_kb / 1024
        fsize_gb = fsize_mb / 1024
        'Pick the right size i.e KB, MB or GB
        If fsize_kb < 1500 Then
            sizeType = "KB"
            returnSize = Format(fsize_kb, "0.00")
        ElseIf fsize_mb >= 1 And fsize_mb < 1000 Then
            sizeType = "MB"
            returnSize = Format(fsize_mb, "0.00")
        ElseIf fsize_gb >= 1 Then
            sizeType = "GB"
            returnSize = Format(fsize_gb, "0.00")
            sizeType = "KB"
            returnSize = Format(fsize_kb, "0.000")
        End If
        Return returnSize & sizeType
    End Function
