Convert Gigabits to Gigabytes
Convert Gigabits (Gbit) to Gigabytes (GB) instantly and accurately.
Conversion Formula
GB = Gbit × 0.125
About Gigabits
A gigabit (Gbit) = 10⁹ bits (SI). 1 Gbit/s Ethernet (1000BASE-T) is the enterprise baseline; 10/25/100/400 Gbit/s are data-centre standards. Bus speeds: PCIe 4.0 ×16 = 256 Gbit/s; Thunderbolt 4 = 40 Gbit/s; HDMI 2.1 = 48 Gbit/s. NVMe SSDs: PCIe 4 ≈ 57 Gbit/s; PCIe 5 > 112 Gbit/s. Submarine cables: 200 Gbit/s per wavelength × hundreds of wavelengths. 1 Gbit = 10⁹ bits = 125 MB.
About Gigabytes
A gigabyte (GB) = 10⁹ bytes (SI). All consumer HDDs, SSDs, SD cards, USB drives, and smartphones advertise in GB. Media sizes: 4K Blu-ray 66-100 GB; 4K Netflix film 10-15 GB; modern AAA PC game 50-200 GB; Google Maps offline country data 5-30 GB. The IBM 350 RAMAC (1956) stored 0.00000375 GB; a Seagate Exos 20 TB holds 20,000 GB - 5.3-million-fold increase in 66 years. 1 GB = 10⁹ bytes = 1,000 MB.
