Gibibyte vs Gigabyte: which is bigger?
A gibibyte is the larger unit: one gibibyte equals 1.073742 gigabytes. Put another way, you need 1.073742 gigabytes to make a single gibibyte.
What is a Gibibyte? History, origin and usage
The gibibyte is the IEC’s binary gigabyte, defined in 1998 as exactly 1,073,741,824 bytes (1,024 cubed) with the symbol GiB; the name fuses “giga” and “binary.” It was standardised to end the long-running ambiguity in which “gigabyte” meant either a billion bytes or 1,024-cubed bytes.
Gibibytes are the precise unit for RAM and for the storage figures shown by many operating systems and technical tools. When a system reports your “GB” of memory or disk, the underlying binary count is usually in gibibytes.
One gibibyte is exactly 1,073,741,824 bytes, about 7.4% larger than a decimal gigabyte. That difference is exactly why a hard drive sold as “1,000 GB” (1 TB) is displayed as roughly 931 GiB by software that counts in binary units.
What is a Gigabyte? History, origin and usage
The gigabyte is a billion bytes in decimal (SI “giga”), but in binary usage it has meant 1,073,741,824 bytes (1,024 cubed). The gap between the two meanings grows with each step up the prefix ladder, which is why the gigabyte is where the decimal-versus-binary dispute becomes very visible to ordinary users.
Gigabytes are the everyday unit for RAM, phone and computer storage, mobile-data allowances and large downloads. Hard-drive and SSD makers sell capacity in decimal gigabytes of 1,000,000,000 bytes each.
The binary unit — 1,073,741,824 bytes — is properly the gibibyte (GiB), about 7% larger than a decimal gigabyte. That 7% is why a drive sold as “1,000 GB” can show up as only about 931 “GB” in some operating systems, a mismatch that has even prompted lawsuits.

Tips for converting Gibibyte to Gigabyte
- To go from gibibyte to gigabyte, multiply by 1.073742; to go back, divide by 1.073742 (or multiply by 0.9313226).
- For a quick mental estimate, remember that 1 gibibyte ≈ 1.073742 gigabyte, so 10 gibibyte ≈ 10.73742 gigabyte.
- 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 Gibibyte to Gigabyte converter
Type a number into the Gibibyte field and the equivalent in Gigabyte 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 Gigabyte field to convert the other way (gigabyte to gibibyte). 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 GiB = 1.073742 GB), 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 gibibyte-to-gigabyte 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
