Convert Gigabytes to Bits (GB to bit)
1 gigabyte (GB) = 8000000000 bits (bit). 1 bit = 1.25 × 10⁻¹⁰ GB. Example: 15 GB = 15 × 8000000000 = 120000000000 bit.

How to Convert Gigabyte to Bit
- 1 GB = 8000000000 bit
- 1 bit = 1.25 × 10⁻¹⁰ GB
- Example: convert 15 GB to bit: 15 GB = 15 × 8000000000 bit = 120000000000 bit
Formula
bit = GB × 8000000000
Derivation from SI units:
- 1 GB = 10⁹ bytes = 8 × 10⁹ bits (decimal, SI).
- The basic unit of information: one binary digit, 0 or 1.
Both units are defined exactly, so the factor is exact. Gigabyte definition: gigabyte; Bit definition: bit.
Worked examples
- A reading of 16 GB converts to 128000000000 bit.
16 GB × 8000000000 = 128000000000 bit - A value of 128 GB is 1024000000000 bit.
128 GB × 8000000000 = 1024000000000 bit
