Use the converter below to change any gigabytes value into bits instantly — with formula, conversion table, and real-world examples.

8,000,000,000

Conversion formula

Forward
bits = gigabytes × 8,000,000,000
Reverse
gigabytes = bits × 1.2500e-10

Example: 10 GB × 8,000,000,000 = 80,000,000,000 b.

About both units

From

Gigabyte

GB

The gigabyte equals 1,000,000,000 bytes (SI) or 1,073,741,824 bytes (binary, GiB). Standard unit for USB drives, SSDs, mobile-data allowances and RAM. A 64 GB phone holds about 15,000 photos.

Real-world: Smartphone: 64 GB / 128 GB / 256 GB typical. PC RAM: 16 GB / 32 GB common. UHD movie: 20–50 GB.

Bit

b

The bit is the smallest unit of digital information — a single 0 or 1. Coined by John Tukey in 1946. Network speeds, modem rates and compression ratios are measured in bits; file sizes and memory in bytes (8 bits each).

Real-world: Home fibre: 100 Mbps = 100,000,000 bps. AES key: 256 bits. MP3 bit rate: 128–320 kbps.

Tips & common mistakes

Quick tips

  • SI: 1 GB = 1000 MB = 10⁹ B. Binary GiB = 2³⁰ B.
  • Hard drives use SI; OS may show binary — discrepancy ~7%.
  • Mobile data plans: SI GB.

Avoid these

  • Expecting 64 GB drive to hold 64 × 1,073,741,824 B — it's 64 × 10⁹ B (7% less by binary measure).
  • Confusing GB with Gb (gigabit, 1/8).
  • Mixing GB and GiB without noting the discrepancy.

Frequently asked questions

How many bits in a gigabyte?
One gigabyte equals 8,000,000,000 bits.
How do I convert gigabytes to bits?
Multiply the gigabyte value by 8,000,000,000 to get the equivalent in bits.
What is 100 gigabytes in bits?
100 gigabytes equals 800,000,000,000 bits.
Is a gigabyte bigger than a bit?
Yes. 1 gigabyte equals 8,000,000,000 bits, so one gigabyte is larger.
How to convert gigabytes to bits without a calculator?
Multiply by 8,000,000,000 for a quick estimate; use a calculator for precise results.
