How to Convert Kilobyte to Byte
To convert Kilobyte (KB) to Byte (B), multiply your value by 1024.
Example: 5 KB × 1024 = 5120 B
What is a Kilobyte?
The kilobyte equals 1,024 bytes in binary (computing) conventions, or 1,000 bytes in decimal SI conventions. The discrepancy arises because computing naturally works in powers of 2, while SI prefixes denote powers of 10. The IEC introduced 'kibibyte' (KiB = 1,024 bytes) to distinguish the two, though 'kilobyte' and 'KB' are widely used for both. A plain-text email without attachments is typically 2–5 kilobytes.
What is a Byte?
The byte is the standard unit of digital storage, equal to 8 bits and capable of encoding 256 distinct values (2⁸). It became the norm with IBM's System/360 in 1964 as the smallest addressable memory unit and remains so in virtually all modern computing architectures. File sizes, RAM, and storage capacities are all measured in bytes or multiples thereof. A single ASCII character requires exactly one byte.

Frequently Asked Questions
How do I convert Kilobyte to Byte?
Multiply the Kilobyte value by 1024. Formula: B = KB × 1024. Example: 10 KB = 10240 B.
How many Byte are in one Kilobyte?
One Kilobyte (KB) equals 1024 Byte (B).
How many Kilobyte are in one Byte?
One Byte (B) equals 0.00097656 Kilobyte (KB).
What is the exact conversion factor from Kilobyte to Byte?
The conversion factor is 1024. Multiply any KB value by this number to get B. For the reverse, multiply by 0.00097656.
How do I convert Byte back to Kilobyte?
Divide by 1024, or equivalently multiply by 0.00097656. Formula: KB = B ÷ 1024.
Is the Kilobyte-to-Byte conversion internationally standardized?
Yes. Both units are defined by international standards (SI or the international yard/pound agreement), so the conversion factor 1024 is exact and universally agreed upon.
