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.

Where data-rate conversions are used

Data-rate conversions explain internet speeds and downloads — bits per second versus bytes per second is the trap that surprises most people.

  • Internet plans are sold in megabits per second (Mbps), but downloads show megabytes per second (MB/s) — divide by 8 to convert.
  • A 100 Mbps connection delivers about 12.5 MB/s at best.
  • Real-world speeds are lower than the headline rate because of overhead and network congestion.

Frequently asked questions

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

1 MB/s equals 1000 kB/s.

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

2 MB/s equal 2000 kB/s.

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

Multiply the rate in MB/s by 1000 to get kB/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.
