Had the same task a while ago. Found some nice code snippet, but don´t have the link anymore.

public static void main (String[]args) {
    for (long num : new long[] { 999,1000,1049,1050,1100,5432, 19999, 654321, 7000000, 7654321, 80010000, 88888888, 9999999 })
        System.out.println(formatNumber(num));
}  

public static String formatNumber(long count) {
    if (count < 1000) return "" + count;
    int exp = (int) (Math.log(count) / Math.log(1000));
    return String.format("%.1f %c", count / Math.pow(1000, exp),"kMGTPE".charAt(exp-1));
}
