    double g = size/1048576;
    double t = size/1073741824;

I love this:

public static String getDynamicSpace(long diskSpaceUsed)
{
    if (diskSpaceUsed <= 0) {
        return "0";
    }

    final String[] units = new String[] { "B", "KiB", "MiB", "GiB", "TiB" };
    int digitGroups = (int) (Math.log10(diskSpaceUsed) / Math.log10(1024));
    return new DecimalFormat("#,##0.#").format(diskSpaceUsed / Math.pow(1024, digitGroups))
            + " " + units[digitGroups];
}
