How do I convert kilobytes back to bytes?

Use the reverse converter: 1 kilobyte equals 1000 B.

Is this converter accurate?

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

Bytes to Kilobytes Converter (B to KB)

Formula

To convert bytes to kilobytes, multiply the value by 0.001.

KB = B × 0.001

Example calculation

Convert 10 B to KB:

10 B × 0.001 = 0.01 KB

Decimal vs binary: KB, MB and GB use powers of 1,000 (SI), while KiB, MiB and GiB use powers of 1,024. Storage makers use decimal units; many operating systems and memory sizes use binary ones, which is why a "500 GB" drive shows less space.

About the units

Byte (B): Eight bits, the basic unit of computer storage and the size of one character in many encodings.
Kilobyte (KB): 1,000 bytes in the decimal (SI) system. Often confused with the kibibyte (1,024 bytes).
