Data Transfer Rate Converter — Data rates come in two flavors: bits per second (used in networking and ISP marketing) and bytes per second (used in file transfer and download managers). 1 byte = 8 bits. Within each flavor, the SI decimal prefixes apply: 1 kbit/s = 1,000 bit/s, 1 Mbit/s = 1,000 kbit/s, and so on.
Conversions run locally in your browser. No values are sent anywhere.

Data Transfer Rate Converter是什么？
Data rates come in two flavors: bits per second (used in networking and ISP marketing) and bytes per second (used in file transfer and download managers). 1 byte = 8 bits. Within each flavor, the SI decimal prefixes apply: 1 kbit/s = 1,000 bit/s, 1 Mbit/s = 1,000 kbit/s, and so on.
This converter uses bit/s as the base and handles all the common combinations.
使用方法
-
Enter a value
Type the rate in any supported unit. The default is 1 Mbit/s.
-
Pick the units
The from/to dropdowns cover bit/s, kbit/s, Mbit/s, Gbit/s, Tbit/s, and the same range in bytes (B/s through TB/s).
-
Note the case
A lowercase "b" means bits (kbit/s); an uppercase "B" means bytes (kB/s). The factor is 8 between them.
示例
100 Mbps internet → MB/s download
A 100 Mbps connection (ISP quote) downloads at about 12.5 MB/s (file transfer speed).
100 Mbit/s
结果： ≈ 12.5 MB/s
