Kilobyte

KB

The kilobyte equals 1000 bytes (SI) or 1024 bytes (binary). In drive marketing and networking, KB = 1000 B. In RAM and some OS contexts, KB = 1024 B. Use KiB when you specifically mean 1024 bytes.

Real-world: Simple text file: 1–10 KB. Webpage HTML: 20–200 KB. Email: typically under 100 KB without attachment.

Tips & common mistakes

Quick tips

  • SI: 1 KB = 1000 B. Binary: 1 KB = 1024 B (KiB).
  • Storage makers use SI; RAM typically binary.
  • Old BIOS messages may show memory as "640K" meaning KiB.

Avoid these

  • Assuming 1 KB always = 1024 B — varies by context.
  • Confusing KB (storage) with Kb (kilobit, 1/8 of KB).
  • Mixing SI and binary without noting which.
