Common mistakes in data rate conversion

  • Broadband's '100 Mbit/s' is megabits, not megabytes: divide by 8 for the download rate in MB/s. 100 Mbit/s gives about 12.5 MB/s, so a 1 GB file takes over a minute, not ten seconds.
  • MB/s (bytes) and Mb/s (bits) differ by a factor of 8, and the letter case is the only visible difference. Gigabit networking at 1 Gbit/s moves 125 MB/s of file data. Always check whether a spec uses the big or the small b.
  • Network speeds always count in decimal: 1 kbit/s = 1,000 bit/s and 1 Mbit/s = 1,000,000 bit/s. Binary prefixes (Kibit/s, Mibit/s, based on 1,024) are a different scale mostly seen in download managers. Don't mix the scales when comparing measured speed against what your ISP promised.

Correct answer: 20.8 megabyte per second = 166 megabit per second.

Definitions

megabyte per second (MB/s)

A unit of data transfer speed equal to 8 megabits per second.

Megabytes per second (MB/s) is often used to measure file transfer speeds or disk I/O. It is important to distinguish this from Mbps (megabits per second), which is 8 times slower.

megabit per second (Mbit/s)

Standard unit for internet connection speeds.

Megabits per second (Mbps or Mbit/s) is the standard unit for measuring bandwidth and internet connection speeds. One megabit per second corresponds to transferring one million bits every second.

byte per second (B/s)

8 bits per second.

One byte per second (B/s) is a rate equal to eight bits per second. It is commonly used in low-level data transfer contexts.

bit per second (bps)

The base unit of data rate. Formally bit/s.

Bit per second (bps) is the primary unit of data transfer rate. While 'bps' is common in informal contexts, 'bit/s' is the formal abbreviation. It should not be confused with B/s (byte per second), where 1 B/s = 8 bps. It is also distinct from 'baud', which refers to symbol rate.

gibibit per second (Gibit/s)

Binary data rate unit (2^30 bits per second).

Gibibit per second (Gibit/s) is a binary unit of data rate defined by the IEC. Unlike the decimal gigabit (10^9 bits), the gibibit is exactly 2^30 bits (1,073,741,824 bits).

Frequently asked questions

What is the difference between Mbps and MB/s?

Mbps is megabits per second, while MB/s is megabytes per second. Since 1 byte = 8 bits, MB/s is 8× larger than Mbps.

How do I convert Mbps to MB/s?

Divide by 8. Example: 100 Mbps ÷ 8 = 12.5 MB/s (theoretical maximum).

Why does my 100 Mbps internet only download at around 10–12 MB/s?

Because the plan is in Mbps (bits), but downloads are shown in MB/s (bytes). Also, real-world speeds are slightly lower due to Wi‑Fi, congestion, and protocol overhead.

How many MB/s is 1 Gbps?

1 Gbps = 1000 Mbps, and 1000 ÷ 8 = 125 MB/s (theoretical maximum).

Is 1 Gbps the same as 1000 Mbps?

Yes. In networking, 1 gigabit per second equals 1000 megabits per second.

What is the difference between bandwidth and latency?

Bandwidth (Mbps) is how much data per second you can transfer. Latency (ms) is the delay before data starts moving. Low latency matters a lot for gaming and videos.

How do I use the data‑rate converter on konvertera.nu?

Enter the speed you have (like Mbps), select the target unit (like MB/s), and the converter will show the equivalent value.
