Quick answer: Kilobyte to Kibibyte
1 Kilobyte = 0.9765625 Kibibyte (KB → KiB). To convert kilobyte to kibibyte, multiply by 0.9765625. To convert kibibyte to kilobyte, multiply by 1.024. The converter at the top does this instantly and both ways; the sections below give the formula, worked examples, a full conversion chart and answers to the most common kilobyte-to-kibibyte questions.
How to convert Kilobyte to Kibibyte
To convert kilobyte to kibibyte, multiply the number of kilobyte by the conversion factor 0.9765625, because 1 KB = 0.9765625 KiB. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 KiB = 1.024 KB, so you divide by 0.9765625 (or multiply by 1.024) to turn kibibyte back into kilobyte.
KiB = KB × 0.9765625 ·
KB = KiB × 1.024
- Write down the value you want to convert, in kilobyte.
- Multiply it by 0.9765625.
- The result is the same area/length/quantity expressed in kibibyte.

Kilobyte vs Kibibyte: which is bigger?
A kibibyte is the larger unit: one kibibyte equals 1.024 kilobytes. Put another way, you need 1.024 kilobytes to make a single kibibyte.
What is a Kilobyte? History, origin and usage
The kilobyte applies the metric “kilo” prefix to the byte. In the strict SI/decimal convention it means exactly 1,000 bytes, but for decades computer memory — naturally sized in powers of two — used “kilobyte” loosely to mean 1,024 bytes, sowing lasting confusion.
Kilobytes describe small files — a page of plain text, a small icon, or a short email. Storage makers and networks use the 1,000-byte decimal kilobyte, while some operating systems have historically displayed the 1,024-byte value under the same “KB” label.
The 1,024-byte unit has its own unambiguous name — the kibibyte (KiB) — standardised by the International Electrotechnical Commission in 1998 precisely to end the “is 1 KB 1000 or 1024?” confusion. The discrepancy is small for kilobytes but compounds at larger scales.
What is a Kibibyte? History, origin and usage
The kibibyte was created in 1998 by the International Electrotechnical Commission (standard IEC 60027-2, later folded into ISO/IEC 80000) to give the binary 1,024-byte unit its own unambiguous name and symbol, KiB. The name fuses “kilo” with “binary,” and it exists precisely to stop “kilobyte” from meaning two different things.
The kibibyte (and its relatives) appear in technical documentation, programming, and some operating systems and Linux tools that want to be precise about powers of two. It is the correct term whenever exactly 1,024 bytes is meant.
One kibibyte is exactly 2 to the 10th power = 1,024 bytes, versus the decimal kilobyte’s 1,000. Despite being the standards-approved term since 1998, “kibibyte” is still far less used in everyday speech than the ambiguous “kilobyte.”

Tips for converting Kilobyte to Kibibyte
- To go from kilobyte to kibibyte, multiply by 0.9765625; to go back, divide by 0.9765625 (or multiply by 1.024).
- For a quick mental estimate, remember that 1 kilobyte ≈ 0.9765625 kibibyte, so 10 kilobyte ≈ 9.765625 kibibyte.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Kilobyte to Kibibyte converter
Type a number into the Kilobyte field and the equivalent in Kibibyte appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Kibibyte field to convert the other way (kibibyte to kilobyte). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 KB = 0.9765625 KiB), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for kilobyte-to-kibibyte conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST — Prefixes for binary multiples — the reference that separates the decimal prefixes (kB = 1,000 bytes) from the IEC binary ones (KiB = 1,024 bytes). This page keeps the two apart rather than silently mixing them, which is the usual source of disagreement between file sizes.
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
This converter uses the <strong>decimal (SI)</strong> convention for KB/MB/GB/TB (1 KB = 1,000 bytes), as used by storage manufacturers and networks. The <strong>binary</strong> units — KiB, MiB, GiB (1 KiB = 1,024 bytes) — are listed separately, because operating systems often label binary sizes with the decimal names.
Frequently asked questions
- How many kibibyte are in 1 kilobyte?
- 1 kilobyte = 0.9765625 kibibyte (KiB). To convert any number of kilobyte to kibibyte, multiply by 0.9765625.
- How do I convert kilobyte to kibibyte?
- Multiply the number of kilobyte by 0.9765625. For example, 10 kilobyte = 10 × 0.9765625 = 9.765625 kibibyte, and 25 kilobyte = 24.41406 kibibyte.
- How many kilobyte are in 1 kibibyte?
- 1 kibibyte = 1.024 kilobyte. So to convert kibibyte back to kilobyte, multiply by 1.024.
- What is the formula to convert kilobyte to kibibyte?
- kibibyte = kilobyte × 0.9765625. The reverse formula is kilobyte = kibibyte × 1.024.
- How much is 100 kilobyte in kibibyte?
- 100 kilobyte = 97.65625 kibibyte. (And 1000 kilobyte = 976.5625 kibibyte.)
- Which is bigger, a kilobyte or a kibibyte?
- A kibibyte is larger: 1 kibibyte = 1.024 kilobyte.
- Is this kilobyte to kibibyte converter accurate?
- Yes — every value is computed from the exact 0.9765625 KiB per KB factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert kibibyte to kilobyte too?
- Yes. The converter works both ways — enter a value in either field. 1 kibibyte = 1.024 kilobyte.
