Gigabytes to Bytes Converter
1 gigabyte = 1,000,000,000 bytes
1 gigabyte equals 1,000,000,000 bytes
How to convert gigabytes to bytes
Lowercase b means bit; uppercase B means byte (8 bits). Decimal kB, MB and GB use powers of 1000; binary KiB, MiB and GiB use powers of 1024. Choose the label that matches the source measurement.
B = GB × 1000000000One gigabyte is 1000000000 bytes, so a single multiplication converts any value.
10,000,000,000 B = 10 × 1000000000Gigabytes to bytes conversion table

byteB
Eight bits. The standard addressable unit of computer memory.
Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
