Convert Bytes to Gigabits (B to Gbit)
1 byte (B) = 8 × 10⁻⁹ gigabits (Gbit). 1 Gbit = 125000000 B. Example: 15 B = 15 × 8 × 10⁻⁹ = 1.2 × 10⁻⁷ Gbit.

How to Convert Byte to Gigabit
- 1 B = 8 × 10⁻⁹ Gbit
- 1 Gbit = 125000000 B
- Example: convert 15 B to Gbit: 15 B = 15 × 8 × 10⁻⁹ Gbit = 1.2 × 10⁻⁷ Gbit
Formula
Gbit = B ÷ 125000000
Derivation from SI units:
- 1 byte = 8 bits (an octet).
- 1 Gbit = 10⁹ bits.
- 1 B = 8 bit ÷ 1000000000 bit per Gbit = 8 × 10⁻⁹ Gbit
Both units are defined exactly, so the factor is exact. Byte definition: byte; Gigabit definition: gigabit.
Worked examples
- A reading of 512 B converts to 0.000004096 Gbit.
512 B × 8 × 10⁻⁹ = 0.000004096 Gbit - A value of 4096 B is 0.000032768 Gbit.
4096 B × 8 × 10⁻⁹ = 0.000032768 Gbit

Where it's used
Bytes are used for file and memory sizes, while gigabits appear in DRAM and NAND flash chip densities. Both measure amount of digital information, so the conversion is a fixed factor.

Frequently asked questions
How many gigabits are in 1 byte?
1 B = 8 × 10⁻⁹ Gbit.
How do I convert bytes to gigabits?
Multiply the value in B by 8 × 10⁻⁹, or divide it by 125000000. For example, 15 B × 8 × 10⁻⁹ = 1.2 × 10⁻⁷ Gbit.
Is the B to Gbit conversion exact?
Yes. Both units are defined exactly, and 1 B is exactly 8 × 10⁻⁹ Gbit.
