Common mistakes to avoid

  • Reading the result the wrong way round. Confirm the answer is in KB, not MB, before you rely on it.
  • Truncating instead of rounding, which compounds error across larger MB values.
  • Mixing bits and bytes — 1 byte = 8 bits, and storage is usually quoted in bytes while bandwidth is often in bits.
