480Mbits

480 Mbits, typically written as 480 Mbps, is a data transfer rate equal to 480,000,000 bits per second. Since a byte consists of eight bits, this rate corresponds to 60,000,000 bytes per second, or about 60 MB/s in decimal terms (roughly 57.2 MiB/s in binary terms). The term is commonly used to describe theoretical or advertised maximums, not guaranteed sustained throughput.

The most familiar association is with USB 2.0 High-Speed, which specifies a signaling rate of 480 Mbps. This is the raw bit rate; actual usable data transfer is lower due to protocol overhead, handshaking, and device-specific factors. Real-world USB 2.0 transfers typically run around 35–40 MB/s (about 280–320 Mbps) under typical conditions.

Other contexts may reference 480 Mbps in wireless or storage interfaces, but the practical data rate depends on multiple factors including channel conditions, encoding efficiency, protocol overhead, and device performance. As technology progressed, newer standards have surpassed the 480 Mbps figure, offering higher maximums and improved efficiency.

Notes: When discussing 480 Mbits, it is important to distinguish bits from bytes and mebibits from megabits. 480 Mbits per second is not the same as 480 megabytes per second, and megabits are not equivalent to mebibits.
