Networks, storage buses, and codecs each choose their own data rate units. This guide lines them up and shows you how to compare throughput fairly.
Bits per second dominate networking, while bytes per second are popular in storage and OS utilities. Keep both in sight to avoid overestimating download times or undersizing links.

Every unit below references the SI base value so you can compare readings quickly.
| Unit | Symbol | 1 unit in bps | Notes |
|---|---|---|---|
| Bits per second | bps | Reference unit | — |
| Bytes per second | B/s | 1 B/s = 8 bps | — |
| Kilobits per second | Kbps | 1 Kbps = 1K bps | — |
| Kilobytes per second | KB/s | 1 KB/s = 8K bps | — |
| Megabits per second | Mbps | 1 Mbps = 1.0000×10^+6 bps | — |
| Megabytes per second | MB/s | 1 MB/s = 8.0000×10^+6 bps | — |
| Gigabits per second | Gbps | 1 Gbps = 1.0000×10^+9 bps | — |
These presets mirror the quick actions available inside the SwapUnits converter.
Plans advertise megabits per second. Downloads often display megabytes per second. Divide the plan speed by 8 to estimate top download speeds before protocol overhead.
Megabits per second (Mbps) count bits. Megabytes per second (MB/s) count bytes. Since one byte equals eight bits, MB/s is smaller numerically but measures actual file size movement.
Use Gbps for datacenter trunks, high-performance storage, or backbone links. Mbps remains the norm for office LANs and consumer connections.
