kB to Bits Converter

How to convert kilobytes to bits

Formulab = kB × 8,000

Multiply the value in kilobytes by 8,000. To go the other way, multiply by 0.000125 (or divide by 8,000).

A kilobyte is larger than a bit: one kilobyte contains 8,000 bits.

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).

Bit (b)

A single binary digit, 0 or 1.

Frequently asked questions

How many bits are in one kilobyte?

There are 8,000 bits in one kilobyte, and this value is exact by definition.

How do I convert kilobytes to bits?

Multiply the number of kilobytes by 8,000. For example, 10 kB × 8,000 = 80,000 b.

How many kilobytes are in one bit?

One bit equals 0.000125 kilobytes. That is the reverse factor, 1 ÷ 8,000.

What is 10 kilobytes in bits?

10 kB = 80,000 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.
