Convert Bytes to Gigabytes
1 byte is 0 GB. One byte is exactly 1e-9 gigabytes.
One byte is 1.0000 × 10^-9 gigabytes. To convert bytes to gigabytes, multiply by 1.0000 × 10^-9; to go the other way, divide by 1.0000 × 10^-9 or multiply by 1000000000. The factor is exact rather than rounded: it follows from IEC 80000-13. Eight bits.

Factors are entered by hand from IEC 80000-13 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert bytes to gigabytes?
- 1.Take the measurement in bytes.
- 2.Multiply by 1.0000 × 10^-9 — that is how many gigabytes fit in one byte.
- 3.To go back the other way, divide by 1.0000 × 10^-9, or multiply by 1000000000.

What are bytes and gigabytes?
- Byte (B)
- Eight bits. The smallest unit storage is actually sold and addressed in.
- Gigabyte (GB)
- Exactly one billion bytes. This is why a "1 TB" drive shows as roughly 931 GB in Windows: the drive is sold in decimal and displayed in binary.
