Convert Bits to Exabytes
Convert Bits (b) to Exabytes (EB) instantly and accurately.
Conversion Formula
EB = b × 1.250000000e-19
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.
About Exabytes
An exabyte (EB) = 10¹⁸ bytes (SI). Global datasphere ≈ 120 EB/year created in 2023, growing ≈ 23%/year. Total installed global storage capacity ≈ 10,000 EB in 2023. AWS total storage estimated > 1,000 EB. Internet Archive stores ≈ 90 PB ≈ 0.09 EB. WGS of all 8 billion humans at 30× would produce ≈ 720 EB of raw FASTQ. Credible NSA Utah Data Centre estimates: 3-100 EB. 1 EB = 10¹⁸ bytes = 1,000 PB.
