Convert Kilobytes to Bytes
1 kilobyte is 1,000 B. One kilobyte is exactly 1000 bytes.
One kilobyte is 1000 bytes. To convert kilobytes to bytes, multiply by 1000; to go the other way, divide by 1000 or multiply by 0.001. The factor is exact rather than rounded: it follows from IEC 80000-13. Exactly 1,000 bytes under the SI prefix, which is what drive manufacturers and network speeds use.

Factors are entered by hand from IEC 80000-13 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert kilobytes to bytes?
- 1.Take the measurement in kilobytes.
- 2.Multiply by 1000 — that is how many bytes fit in one kilobyte.
- 3.To go back the other way, divide by 1000, or multiply by 0.001.

What are kilobytes and bytes?
- Kilobyte (kB)
- Exactly 1,000 bytes under the SI prefix, which is what drive manufacturers and network speeds use. Not 1,024 — that is the kibibyte.
- Byte (B)
- Eight bits. The smallest unit storage is actually sold and addressed in.
