How to Convert Bytes to Gigabytes
To convert bytes to gigabytes, divide by 1,000,000,000. This gives you the equivalent storage size in the target unit. Learn more: Gigabytes to Bytes converter.
B: A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). Try the Bytes to Gibibytes.
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. You might also need: Pb → GB.
1 B = 0.000000001 GB (using SI decimal standard) — or equivalently, 1 GB = 1,000,000,000B.
B to GB Conversion Formula
// Convert B to GB
GB = B × 0.000000001
// Reverse: Convert GB to B
B = GB × 1,000,000,000Byte to Gigabyte Conversion Examples
100 B = 0.0000001 GB
256 B = 0.000000256 GB
500 B = 0.0000005 GB
1,000 B = 0.000001 GB
2,048 B = 0.000002048 GB
What Is a Byte (B)? Definition and Uses
A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). Try the convert Zib to Tb.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: EiB/s to Zibps calculator.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) See also: B to Zb converter.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 B.
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. See also: Yb to GB.
The gigabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Learn more: Exbibits in Kilobits.
Common uses: Movies, video games, smartphone storage, USB drives, cloud storage plans Try the converting Bits Per Second to Kilobytes Per Second.
1 GB = 8 × 10⁹ bits = 1 × 10⁹ bytes.
The gigabyte can be abbreviated as GB; for example, 1 gigabyte can be written as 1 GB.

SI Decimal vs Binary: Why Two Different Standards?
When converting bytes 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.
