How to Convert Kilobytes to Gigabytes
To convert kilobytes to gigabytes, divide by 1,000,000 (using SI decimal). Both units measure storage capacity—the difference is scale. See also: convert GB to KB.
KB: A kilobyte is 1,000 bytes using the SI decimal standard. Commonly used for small file sizes. Try the KB → MiB.
GB: A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use. Use our Yobibytes to Gigabytes.
1 KB = 0.000001 GB (using SI decimal standard) — or equivalently, 1 GB = 1,000,000KB.
KB to GB Conversion Formula
// Convert KB to GB
GB = KB × 0.000001
// Reverse: Convert GB to KB
KB = GB × 1,000,000Kilobyte to Gigabyte Conversion Examples
100 KB = 0.0001 GB
256 KB = 0.000256 GB
500 KB = 0.0005 GB
1,000 KB = 0.001 GB
2,048 KB = 0.002048 GB
Binary Standard (Base 1024)
Using binary calculation: 1 KB = 0.000000953674316 GB
100 KB = 0.000095367431641 GB
1,000 KB = 0.000953674316 GB
1,024 KB = 0.0009765625 GB
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. Use our Bytes to Terabits converter.
The kilobyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our Tebibits Per Second to Petabits Per Second calculator.
Common uses: Text documents, small images, email attachments, configuration files Check out our convert Kilobytes to Exabits.
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 Gigabyte (GB)? Definition and Uses
A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use. You might also need: Zettabits to Gigabytes conversion.
The gigabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our KiB to Gibibytes converter.

SI Decimal vs Binary: Why Two Different Standards?
When converting kilobytes to gigabytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| 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.
