1,000 bytes
= 0.000001 GB= 0.001 MB
equals 1,000 bytesFormula: B = kB × 1000
Kilobyte to Byte formula
B = kB × 1000
Convert 5 kilobytes to bytes
- Start with 5 kilobytes.
- Multiply by the conversion factor: 5 × 1,000 = 5,000.
- So 5 kB = 5,000 B.

Unit definitions
What is a kilobyte?
The kilobyte (decimal) is exactly 1000 bytes under the SI convention used by storage manufacturers and networking. It should not be confused with the kibibyte (1024 bytes). Small text files and icons are measured in kilobytes.
What is a byte?
The byte is eight bits, the basic addressable unit of computer memory and storage. One byte can represent a single text character in older encodings. It is the reference unit from which kilobytes, megabytes, and their binary counterparts are built.
Frequently asked questions
How many bytes are in one kilobyte?
One kilobyte equals 1,000 bytes (1 kB = 1,000 B).
How do I convert kilobytes to bytes?
Multiply the value in kilobytes by 1,000. For example, 10 kB × 1,000 = 10,000 B.
Which is bigger — a kilobyte or a byte?
A kilobyte is bigger: one kilobyte contains 1,000 bytes.
Is this kilobyte to byte converter free?
Yes — the converter is free, works offline once loaded, and computes instantly in your browser without sending your numbers to a server.
