Gibibyte (GiB)
Definition: Equal to exactly 1,073,741,824 bytes (2^30), the precise binary counterpart to the decimal gigabyte.
History: Part of the same 1998 IEC binary-prefix standard as the kibibyte and mebibyte, created so operating systems and software could report storage in unambiguous power-of-two units instead of silently overloading the term "GB."
Current use: Used by Linux utilities such as "free" and "df" that explicitly label binary sizes as GiB, and implicitly by older Windows storage displays and RAM specifications, where 1 GiB memory modules are the physical norm.
Tebibyte (TiB)
Definition: Equal to exactly 1,099,511,627,776 bytes (2^40), the precise binary counterpart to the decimal terabyte.
History: The largest commonly used unit in the IEC's 1998 binary-prefix system, adopted as storage capacities grew into the terabyte range and a precise binary label became necessary alongside the decimal terabyte used in marketing.
Current use: Used in enterprise storage systems, data center capacity planning, and by operating system utilities that report binary-accurate free space on very large drives, RAID arrays, and network-attached storage.

About These Parameters
- Value
- The number you want to convert, expressed in the "From" unit. Accepts decimals.
- From Unit
- The unit your input value is currently measured in.
- To Unit
- The unit you want the result converted into. Use the swap button to flip From and To instantly.
How Data Storage Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to the byte. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Gibibyte → Tebibyte: multiply by 0.0009765625. For example, 1 GiB × 0.0009765625 = 0.0009765625 TiB.
Decimal (1000) vs. Binary (1024)
Data storage is the one measurement family where the same prefix means two different things. Storage manufacturers, and the SI and IEC standards bodies, define a kilobyte as exactly 1,000 bytes, a megabyte as 1,000,000 bytes, and so on — clean powers of ten, matching every other metric prefix. But because computer memory is physically organized in powers of two, operating systems have long used the same labels — "KB," "MB," "GB" — to mean powers of 1,024 instead: 1,024 bytes, 1,048,576 bytes, and so on. This converter treats the decimal units (kilobyte, megabyte, gigabyte, terabyte) and the binary units (kibibyte, mebibyte, gibibyte, tebibyte) as distinct, precisely defined units so there is no ambiguity — 1 kilobyte is always 1,000 bytes, and 1 kibibyte is always 1,024 bytes.
This is exactly why a drive advertised as "500 GB" (500,000,000,000 bytes under the manufacturer's decimal definition) shows up as roughly "465 GB" in Windows' File Explorer — Windows is dividing that same byte count using binary gibibyte math (2^30 bytes per unit) while still displaying the label "GB" instead of the technically correct "GiB." No storage is missing; two different definitions of the same word are being compared.
Bits vs. Bytes: Why Network Speeds Look Slower Than They Are
Internet and Wi-Fi speeds are almost always advertised in bits per second (Mbps or Gbps), while file sizes and download progress bars are shown in bytes (MB or GB) — and there are 8 bits in a byte. A connection advertised as "100 Mbps" therefore has a real-world maximum download speed of about 100 ÷ 8 = 12.5 megabytes per second, not 100 megabytes per second. This single unit mismatch is one of the most common sources of confusion in consumer networking, and it is worth double-checking whenever comparing an advertised connection speed to an actual download time.
Example
1 GiB equals 0.0009765625 TiB. For scale, that's about 214.75× a typical high-resolution smartphone photo (5 MB, or 0.0046566129 GiB).
Frequently Asked Questions
How many Tebibytes are in 1 Gibibyte?
1 Gibibyte (GiB) equals exactly 0.0009765625 Tebibytes (TiB).
Why does my new hard drive show less space than advertised?
Manufacturers advertise capacity using decimal gigabytes (1 GB = 1,000,000,000 bytes), while your operating system typically calculates and displays free space using binary gibibytes (1 GiB = 1,073,741,824 bytes) but still labels it "GB." The byte count is identical — only the unit definition used to display it differs, so a 500 GB drive reads as about 465 "GB" in Windows.
What is the difference between a bit and a byte?
A bit is a single binary digit (0 or 1); a byte is a group of 8 bits and is the smallest unit typically used to represent a character of data. Network and internet speeds are conventionally measured in bits per second, while file and storage sizes are measured in bytes, so an "8 Mbps" connection transfers roughly 1 megabyte per second at best.
Should I use KB/MB/GB or KiB/MiB/GiB?
Use the decimal units (KB, MB, GB, TB) when matching a manufacturer's advertised storage capacity or a network speed. Use the binary units (KiB, MiB, GiB, TiB) when you need the exact power-of-two value a computer uses internally, such as memory addressing or precise free-space reporting — this converter supports both so you can convert accurately between either system.
