Digital Data Storage Conversions

Digital data-storage size conversions for IT, networking, storage-array engineering, datacenter capacity planning, cloud-cost reconciliation, embedded systems and scientific data acquisition: bit, byte, decimal SI ladder (kbit/kB, Mbit/MB, Gbit/GB, Tbit/TB, Pbit/PB) and binary IEC 80000-13 ladder (Kibit/KiB, Mibit/MiB, Gibit/GiB, Tibit/TiB, Pibit/PiB). 1 byte = 8 bits exactly across both ladders. Decimal kB = 1,000 bytes; binary KiB = 1,024 bytes — kept as strictly distinct unit IDs and page names. Data-storage size only — strictly distinct from data-transfer rate (bit/s, MB/s), download-time calculators, bandwidth, compression ratios and storage pricing, none of which are deterministic single-factor conversions.
