Bits to kB Converter

How to convert bits to kilobytes

FormulakB = b × 0.000125

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

A bit is smaller than a kilobyte: it takes 8,000 bits to make one kilobyte.

About the units

Bit (b)

A single binary digit, 0 or 1.

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).

Frequently asked questions

How many kilobytes are in one bit?

There are 0.000125 kilobytes in one bit, and this value is exact by definition.

How do I convert bits to kilobytes?

Multiply the number of bits by 0.000125. For example, 10 b × 0.000125 = 0.00125 kB.

How many bits are in one kilobyte?

One kilobyte equals 8,000 bits. That is the reverse factor, 1 ÷ 0.000125.

What is 10 bits in kilobytes?

10 b = 0.00125 kB.

Is this b to kB 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.
