How this works & FAQ
How many bits are in a byte?
There are 8 bits in a byte. Type a value into the Bits or Bytes field above and every other unit (KB, MB, GB, TB) updates automatically.
What's the difference between KB and KiB (1000 vs 1024)?
1024-based units (KiB, MiB, GiB) match how operating systems typically report file sizes, using powers of 1024. 1000-based units (KB, MB, GB) match how storage manufacturers advertise capacity, using powers of 1000. Switch between them with the toggle above.
How do I convert bytes to KB or MB?
Enter the byte value into the Bytes field — the KB, MB, GB, and TB fields update instantly using whichever base (1000 or 1024) you've selected.
