Data Storage Converter

Digital data conversion is essential in computing, networking, storage, and software development. Our data converter supports both decimal (SI) units used by hard drive manufacturers and binary (IEC) units used by operating systems, as well as data transfer rate units.

Decimal (SI) vs Binary (IEC) Units

A frequent source of confusion: storage manufacturers use decimal prefixes (1 KB = 1,000 bytes) while operating systems use binary prefixes (1 KiB = 1,024 bytes). This is why a '1 TB' hard drive shows as ~931 GiB in Windows or macOS. Decimal: bit (b), Byte (B), Kilobyte (KB=1,000 B), Megabyte (MB=10^6 B), Gigabyte (GB=10^9 B), Terabyte (TB=10^12 B), Petabyte (PB=10^15 B). Binary (IEC): Kibibyte (KiB=1,024 B), Mebibyte (MiB=1,024 KiB), Gibibyte (GiB=1,024 MiB), Tebibyte (TiB=1,024 GiB).

Data Transfer Rates

Network speeds are measured in bits per second (not bytes). 1 Mbps = 1,000,000 bits/s ≈ 125 KB/s (divide by 8 to get bytes). A 100 Mbps internet connection transfers about 12.5 MB per second.
