Common pitfalls and look-alike units
This page uses SI decimal units: 1 KB = 1000 B. Binary contexts use KiB (1 KiB = 1024 B). Drive makers label in decimal while operating systems often display binary, which is why a 500 GB drive shows about 465 GiB — expected, not a defect.
Frequently asked questions
How many bytes are in a kilobyte?
1 kilobyte (KB) equals 1000 byte (B).
How do I convert kilobytes to bytes?
Multiply the kilobyte value by 1000 to get byte — for example, 2 kilobytes = 2000 byte. Note: this page uses SI decimal units (1 KB = 1000 B). Binary units (KiB/MiB, 1 KiB = 1024 B) give different values.
How do I convert bytes back to kilobytes?
1 byte equals 0.001 kilobyte. Use the swap button or the reverse conversion page linked on this page.
