bytes, KB, MB, GB and TB
About this calculator
Bits, bytes, kilobytes, megabytes, gigabytes, terabytes — and the tricky part: decimal (SI) versus binary (IEC) prefixes. Enter a data size in any unit and see all equivalents, with both interpretations shown (1 GB = 1,000 MB vs 1 GiB = 1,024 MiB). It explains why your "1 TB" drive shows up as 931 GB.
Tip: internet speeds are sold in megabits (Mb), but downloads display in megabytes (MB) — divide by 8 to convert, so 100 Mbps is about 12.5 MB/s.
