Convert Terabytes to Gigabits
Convert Terabytes (TB) to Gigabits (Gbit) instantly and accurately.
Conversion Formula
Gbit = TB × 8000
About Terabytes
A terabyte (TB) = 10¹² bytes (SI). Consumer HDDs: 1-22 TB; consumer NVMe SSDs: 1-8 TB. LTO-9 tape: 18 TB/cartridge; enterprise libraries: hundreds of petabytes. Whole genome sequencing: Illumina NovaSeq 6000 run ≈ 6 TB raw FASTQ. JWST downlinks ≈ 57 GB/day (≈20 TB/year). 4K NVR (64 cameras) ≈ 1 TB/day. 1 TB = 10¹² bytes = 1,000 GB.
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.
