About Kilobytes

A kilobyte (KB) = 1,000 bytes (SI). Used by all storage manufacturers (HDD, SSD, USB, SD) and endorsed by the IEC and FTC. Typical sizes: plain-text email 2-5 KB; HTML page 10-100 KB; Word document 10-30 KB. Ethernet MTU = 1,500 bytes ≈ 1.5 KB; jumbo frames 9 KB. MP3 at 128 kbit/s = 16 KB/s of audio. 1 KB = 1,000 bytes = 8,000 bits.

About Yottabytes

A yottabyte (YB) = 10²⁴ bytes (SI) - among the largest original SI named powers. Global annual data generation forecast ≈ 175 ZB = 0.000175 YB by 2025 (IDC) - a yottabyte equals ≈ 5,700 years of data production at 2025 rates. Claims of multi-YB NSA data centres were debunked; credible estimates: 3-100 EB. Erasing 1 YB at the Landauer limit (300 K) would require ≈ 182 J - enough to heat 0.4 mL of water by 1°C. 1 YB = 10²⁴ bytes = 1,000 ZB.
