1 gibibyte equals 1,073,740,000 bytes
How to convert gibibytes 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 = GiB × 1073741824One gibibyte is 1073741824 bytes, so a single multiplication converts any value.
10,737,400,000 B ≈ 10 × 1073741824Gibibytes to bytes conversion table

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.
