What is a kibibyte (KiB)?

A kibibyte (KiB) is a binary unit of data equal to 1024 bytes, defined by the IEC standard. It differs from a kilobyte (KB), which equals 1000 bytes in the SI decimal system. Most operating systems and RAM specs use the binary (KiB) definition.

How many bits are in a kibibyte?

Exactly 8192 bits. Since 1 KiB = 1024 bytes and 1 byte = 8 bits, 1 KiB = 1024 × 8 = 8192 bits.

What is the formula to convert bits to kibibytes?

KiB = bits ÷ 8192. Alternatively: divide by 8 to get bytes, then divide by 1024 to get kibibytes.

Why use KiB instead of KB?

KiB (kibibyte = 1024 bytes) is unambiguous. KB is ambiguous — storage manufacturers use 1000 bytes while OS and RAM specs use 1024 bytes. When precision matters, use KiB.

How accurate is this converter for very large values?

Results use JavaScript 64-bit floating-point arithmetic, accurate up to 2^53 (around 9 quadrillion). That covers virtually all practical bit-to-KiB conversions.

Summary

This tool converts bits to kibibytes (KiB) using the IEC binary standard, where 1 kibibyte equals exactly 1024 bytes, and 1 byte equals exactly 8 bits — making 1 KiB = 8192 bits. Kibibytes are the precise binary unit used by operating systems and memory hardware, as opposed to kilobytes (KB), which use the SI decimal definition of 1000 bytes. Use this converter when working with binary protocols, memory specs, or any context where the exact power-of-two definition matters.

How it works

Enter the number of bits in the input field.
The converter divides by 8 to get bytes, then divides by 1024 to get kibibytes.
Formula: KiB = bits ÷ 8192
