How many bits are in one kilobyte?

There are 8,000 bits in 1 kilobyte.

How do you convert bits to kilobytes?

Multiply the number of bits by 0.000125 — or use the formula kB = b ÷ 8,000.

What is 32 bits in kilobytes?

32 bits is 0.004 kilobytes. 32 ÷ 8,000 = 0.004 kilobytes.

Is the bits to kilobytes conversion exact?

Yes. The relationship is fixed by definition, so 0.000125 is an exact conversion factor — only the displayed result is rounded.

Bits to Kilobytes formula

kB = b ÷ 8,000

The bits to kilobytes conversion factor is 0.000125, which is exact by definition. 1 bit = 0.000125 kilobytes, and 1 kilobyte = 8,000 bits.

Worked examples

2 bits = 0.00025 kilobytes — 2 ÷ 8,000 = 0.00025 kilobytes
32 bits = 0.004 kilobytes — 32 ÷ 8,000 = 0.004 kilobytes
256 bits = 0.032 kilobytes — 256 ÷ 8,000 = 0.032 kilobytes

When you need to convert bits to kilobytes

Checking whether a file fits inside a storage or upload limit.
Working out how much of a mobile data allowance a download will use.
Reconciling the capacity printed on a drive with the smaller figure the operating system reports.

Common mistakes to avoid

Dividing when you should multiply. Because 1 bit = 0.000125 kilobytes, the answer should be smaller than the number you started with.
Treating 1 kB as 1,024 bytes. Storage and network figures use decimal units of 1,000; operating systems usually report binary units of 1,024, which is why a 1 TB drive shows as about 931 GiB.
Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round to two decimals for human-readable sizes. When you are checking a hard limit, use the exact figure: a file 0.4% over an upload cap still fails.

How these units are defined

Bit (b): The smallest unit of digital information. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
Kilobyte (kB): 1,000 bytes in decimal (SI) notation. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
