The byte
A byte is 8 bits — the smallest addressable unit on virtually every modern computer. ASCII text is one byte per character; UTF-8 ranges from 1 to 4 bytes per character.
Bytes to Gigabytes Converter
1 B = 1.0000 × 10^−9 GB
1 byte equals 1.0000 × 10^−9 gigabytes. To convert bytes to gigabytes, multiply the byte value by 1.0000 × 10^−9. For quick reference: 1 B = 1.0000 × 10^−9 GB, 5 B = 5.0000 × 10^−9 GB, 10 B = 1.0000 × 10^−8 GB, 100 B = 1.0000 × 10^−7 GB.

About the byte and the gigabyte
The gigabyte
The gigabyte (GB) equals 1,000,000,000 bytes. The difference between GB (decimal) and GiB (binary, 1,073,741,824 B) is the reason a '1 TB' drive shows as ~931 GB in Windows.
