kB to Bytes Converter

How to convert kilobytes to bytes

FormulaB = kB × 1,000

Multiply the value in kilobytes by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).

A kilobyte is larger than a byte: one kilobyte contains 1,000 bytes.

About the units

Kilobyte (kB)

1,000 bytes (decimal). Some software still uses “KB” for 1,024 bytes; that is properly a kibibyte (KiB). One kilobyte equals 8,000 bits (b).

Byte (B)

Eight bits; the basic addressable unit of memory. One byte equals 8 bits (b).

Frequently asked questions

How many bytes are in one kilobyte?

There are 1,000 bytes in one kilobyte, and this value is exact by definition.

How do I convert kilobytes to bytes?

Multiply the number of kilobytes by 1,000. For example, 10 kB × 1,000 = 10,000 B.

How many kilobytes are in one byte?

One byte equals 0.001 kilobytes. That is the reverse factor, 1 ÷ 1,000.

What is 10 kilobytes in bytes?

10 kB = 10,000 B.

Is this kB to B converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
