KB, MB, GB — decimal or binary?
Storage units come in two flavours: decimal (1 GB = 1000 MB), used by drive makers and networks, and binary (1 GiB = 1024 MiB), used by operating systems. This converter offers both unit families, which is why a “500 GB” drive showing as 465 “GB” in your file manager isn’t missing anything — the OS is counting in GiB.
Bits vs bytes
Network speeds are quoted in bits per second, file sizes in bytes — eight bits to the byte. A 100 Mbps connection moves at most 12.5 MB/s, so a 2.5 GB game download takes around 3½ minutes at full speed. Mixing the two up is the most common data-size mistake there is.
