Why is 1 KB = 1024 bytes and not 1000?

Computers use binary (base 2). 1024 = 2¹⁰ is the natural 'kilo' for computing hardware and memory addressing.

Is KB the same as kB or Kb?

KB = kilobyte (1024 bytes, uppercase K); Kb = kilobit (128 bytes, lowercase b); kB sometimes means kilobyte too. Always check context.

Convert 100 KB to bytes

100 KB × 1024 bytes/KB = 102,400 bytes.

What's the relationship: KB, MB, GB?

1024 KB = 1 MB; 1024 MB = 1 GB; 1024 GB = 1 TB. All powers of 1024 in binary computing.

Key Formulas

Megabyte → Gigabyte

GB = MB × 0.000976563

Gigabyte → Megabyte

MB = GB × 1024

Gigabyte → Terabyte

TB = GB × 0.000976563

Terabyte → Gigabyte

GB = TB × 1024

Formula

bytes = KB × 1024

One kilobyte equals exactly 1024 bytes by the JEDEC binary standard used throughout computing. Unlike SI prefixes (where kilo = 1000), computing uses 1024 (2¹⁰) because computers address memory in powers of 2. This binary foundation reflects how digital systems are fundamentally built and maintained from the earliest designs to modern systems.
