Bits vs. bytes — why 100 Mbit/s is only 12.5 MB/s

Internet providers advertise speed in bits per second (Mbit/s), but downloads and your file manager show bytes per second (MB/s). Because 1 byte is made of 8 bits, you divide the advertised bitrate by 8: a 100 Mbit/s line delivers at most 12.5 MB/s, and a 1 Gbit/s line at most 125 MB/s. The SI prefixes are decimal: 1 Mbit/s = 1000 kbit/s, 1 Gbit/s = 1000 Mbit/s. In practice protocol overhead makes the real rate a little lower.

Data-rate conversions are exact and rest on fixed factors — for more unit pairs, use our data rate conversion hub, and for file sizes (GB, MB, KB) the data storage conversion hub.

Frequently asked questions

How much is 1 kB/s in Mbit/s?

1 kB/s equals 0.008 Mbit/s.

How much is 2 kB/s in Mbit/s?

2 kB/s equal 0.016 Mbit/s.

How do I convert kB/s to Mbit/s?

Divide the rate in kB/s by 125 to get Mbit/s.

Why does my 100 Mbit/s line only download at 12.5 MB/s?

Internet providers quote speed in bits per second (Mbit/s), but downloads and your file manager show bytes per second (MB/s). Since 1 byte = 8 bits, you divide the bitrate by 8: 100 Mbit/s ÷ 8 = 12.5 MB/s. That is the maximum download rate; in practice overhead makes it a little lower.

Is 1 Mbit/s equal to 1000 kbit/s or 1024 kbit/s?

Data rates use decimal (SI) prefixes: 1 kbit/s = 1000 bit/s, 1 Mbit/s = 1000 kbit/s, 1 Gbit/s = 1000 Mbit/s. That is how ISPs and networking gear quote bandwidth — unlike binary memory (1 Kibit = 1024 bit).

What are these data-rate units used for?

bit/s, kbit/s, Mbit/s, and Gbit/s measure bandwidth — internet plans, Wi-Fi, and LAN are advertised this way. kB/s, MB/s, and GB/s measure actual transfer rates, as your browser, download manager, and backup tools display them. The factor of 8 (1 byte = 8 bits) links the two.
