Gigabits to Bytes Converter
1 gigabit = 125,000,000 bytes
1 gigabit equals 125,000,000 bytes
How to convert gigabits 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 × 125000000One gigabit is 125000000 bytes, so a single multiplication converts any value.
1,250,000,000 B = 10 × 125000000Gigabits to bytes conversion table

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.
