Example: 10 GB × 8,000 = 80,000 Mbps.

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.

Megabit per Second

Mbps

Megabits per second (Mbps) is the standard ISP and network-speed unit. 100 Mbps equals 12.5 MB/s download speed. 1 Gbps = 1000 Mbps. Note that marketing "up to" speeds are peak, not sustained.

Real-world: Home fibre: 100–1000 Mbps. 4G mobile: 10–50 Mbps. 5G: 100–1000+ Mbps. Wi-Fi 6: up to 9.6 Gbps theoretical.

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.
