Kilobytes (KB) to Kibibytes (KiB) Converter

How to Convert Kilobytes to Kibibytes

To convert kilobytes (decimal/SI) to kibibytes (binary/IEC), multiply by 0.9765625. Decimal units use base 1,000, while binary units use base 1,024. Use our Kibibytes to Kilobytes converter.

KB is a decimal (SI) unit—what storage manufacturers advertise. 1 KB = 1,000 of the smaller unit. Use our Kilobytes to Terabytes.

KiB is a binary (IEC) unit—what operating systems often display. 1 KiB = 1,024 of the smaller unit. Related: Kib → KiB.

1 KB = 0.9765625 KiB (using SI decimal standard) — or equivalently, 1 KiB = 1.024KB.

KB to KiB Conversion Formula

// Convert KB to KiB
KiB = KB × 0.9765625

// Reverse: Convert KiB to KB
KB = KiB × 1.024

Kilobyte to Kibibyte Conversion Examples

What Is a Kilobyte (KB)? Definition and Uses

A kilobyte is 1,000 bytes using the SI decimal standard. Commonly used for small file sizes. Check out our convert PiB to GB.

The kilobyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Learn more: EiB/s to Eibps calculator.

Common uses: Text documents, small images, email attachments, configuration files Check out our KB to B converter.

1 KB = 8,000 bits = 1,000 bytes.

The kilobyte can be abbreviated as KB; for example, 1 kilobyte can be written as 1 KB.

What Is a Kibibyte (KiB)? Definition and Uses

A kibibyte is 1,024 bytes using the IEC binary standard. More accurately represents computer memory addressing. Learn more: nibble to KiB.

The kibibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Related: Yobibytes in Kibibits.

Common uses: RAM specifications, operating system file sizes, memory allocation Try the converting Kilobits Per Second to Bytes Per Second.

1 KiB = 8,192 bits = 1,024 bytes.

The kibibyte can be abbreviated as KiB; for example, 1 kibibyte can be written as 1 KiB.

SI Decimal vs Binary: Why Two Different Standards?

When converting kilobytes to kibibytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:

SI decimal vs binary storage standards: base, kilobyte size and common users
Standard	Base	1 KB equals	Used By
SI Decimal	1000	1,000 bytes	Hard drive manufacturers, macOS, network speeds
Binary (IEC)	1024	1,024 bytes	Windows, Linux (partially), RAM specifications

Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
