Convert Terabytes to Bits
Convert Terabytes (TB) to Bits (b) instantly and accurately.
Conversion Formula
b = TB × 8000000000000
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 Bits
The bit (b) is the fundamental unit of digital information - a single binary digit: 0 or 1. Coined by John Tukey in 1948; formalised by Claude Shannon. Physically realised as transistor states (SRAM/DRAM), magnetic domains (HDD), charge levels in NAND flash (MLC=2, TLC=3, QLC=4 bits per cell). Shannon entropy: a coin flip = 1 bit; a card drawn from a 52-card deck ≈ 5.7 bits. 1 bit = 1/4 nibble = 1/8 byte.
