How Many Bits in a Gigabyte?

Quick Answer

There are approximately 8.6 billion bits in a gigabyte.

1 GiB = 1,073,741,824 × 8 ≈ 8.59 billion bits

Understanding the Conversion

One binary gigabyte (GiB) = 1,073,741,824 bytes × 8 = 8,589,934,592 bits (≈8.59 billion bits). This is why gigabit internet (1 Gbps) downloads files at about 125 MB per second — 1 billion bits per second ÷ 8 = 125 MB/s.

Formula

1 GiB = 1,073,741,824 × 8 ≈ 8.59 billion bits
