Convert Exabytes to Zettabytes
Convert Exabytes (EB) to Zettabytes (ZB) instantly and accurately.
Conversion Formula
ZB = EB × 0.001
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.
About Zettabytes
A zettabyte (ZB) = 10²¹ bytes (SI). The 'zettabyte era' was declared by Cisco in 2016 when annual IP traffic first crossed 1 ZB. Global IP traffic ≈ 4.8 ZB/year in 2022. Total data-centre capacity worldwide ≈ 10 ZB in 2023. Global datasphere forecast: 175 ZB/year created by 2025 (IDC). Erasing 1 ZB at the Landauer limit (300 K) would require ≈ 22.8 J - a tiny energy cost that thermodynamic limits will not bite for decades. 1 ZB = 10²¹ bytes = 1,000 EB.
