Bits to Gigabits Converter
1 bit = 1e-9 gigabits
1 bit equals 1e-9 gigabits
How to convert bits to gigabits
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.
Gb = b ÷ 1000000000One gigabit corresponds to 1000000000 bits, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.
1e-8 Gb = 10 ÷ 1000000000Bits to gigabits conversion table

About these units
bitb
The smallest unit of digital information: a single binary digit.
gigabitGb
Exactly 1,000,000,000 bits.
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.
