B, KB, MB, GB, TB (binary).
Converts between bytes, kilobytes, megabytes, gigabytes, and terabytes.
Binary (1 KB = 1,024 B) vs decimal (1 kB = 1,000 B) — the calculator uses binary (1024).
This binary-vs-decimal split traces back to computer memory being naturally organized in powers of two, while storage manufacturers market drives using the more familiar decimal system — the gap between the two grows larger the bigger the number, which is why it's most noticeable on large drives.
1 GB = 1,024.00 MB (binary).
Manufacturers use decimal GB (10^9). Operating systems often report in binary (2^30 = 1.074 × 10^9), so a '1 TB' drive shows as ~931 GiB.
1 byte = 8 bits. Networks quote in bits/sec (Mbps); files usually in bytes (MB).
GiB (gibibyte) explicitly means the binary 1,024-based unit, while GB technically means the decimal 1,000-based one — the terms exist specifically to remove the ambiguity that causes the 'missing storage' confusion.
