Byte Units

Utility classes for converting between granularities of SI and IEC byte units and bit units.

Example Usage

What's the difference in hard drive space between perception and actual?

long perception = BinaryByteUnit.TEBIBYTES.toBytes(2);
long usable = DecimalByteUnit.TERABYTES.toBytes(2);
long lost = BinaryByteUnit.BYTES.toGibibytes(perception - usable);
System.out.println(lost + " GiB lost on a 2TB drive.");

Method parameter for specifying a resource size.

public void installDiskCache(long count, ByteUnit unit) {
  long size = unit.toBytes(count);
  // TODO Install disk cache of 'size' bytes.
}

Print human-readable strings for byte and bit amounts.

long bytes = 2 * 1024 * 1024 * 1024;
System.out.println(BinaryByteUnit.format(bytes));
