    return megaByteFormat.format((double) byteCount / (1024 * 1024));
if (byteCount >= 1024) {
    NumberFormat kiloByteFormat = new DecimalFormat("0 KB", new DecimalFormatSymbols(locale));
    return kiloByteFormat.format((double) byteCount / 1024);

double displayAmount = (double) amount;
int unitPowerOf1024 = 0;
if (amount <= 0) {
    return "0 B";
while (displayAmount >= 1024 && unitPowerOf1024 < 4) {
