How to convert kilobytes to bytes
Kilobytes and Bytes both measure data, so converting is a single multiplication. One KB equals 1,000 B, so you multiply your kilobytes value by 1,000.
Formula: bytes = kilobytes × 1,000. For example, 10 KB = 10,000 B.

Kilobytes and Bytes explained
Kilobytes (KB): One thousand bytes (decimal), used for small files.
Bytes (B): Eight bits, the basic unit for file sizes.
When you'd convert kilobytes to bytes
You'll convert kilobytes to bytes whenever a measurement is given in one unit but you need it in the other — comparing kilobytes and bytes figures across regions, following a recipe or spec, or double-checking a number. Because 1 KB is exactly 1,000 B, the result is precise every time.
Frequently asked questions
How many bytes are in a kilobyte?
One KB equals 1,000 B. Multiply your kilobytes figure by 1,000 to get bytes.
What is the formula to convert kilobytes to bytes?
bytes = kilobytes × 1,000. The factor 1,000 is exact.
What is 2 kilobytes in bytes?
2 KB = 2,000 B. You can enter any value in the converter above to get an instant result.
Is this Kilobytes to Bytes converter accurate?
Yes. It uses the standard conversion factor (1 KB = 1,000 B) defined by IEC 80000-13 — units of information (bit, byte), so results are exact to several decimal places.
