Difference between Mbps, Mb/s, MB/s, Gbps, GB/s

As you may have noticed in everyday life, Mbps is the universal speed unit used by telecom companies and manufacturers when announcing and advertising new mobile phone products. Home broadband speeds of 50 and 100 Mbps are commonly discussed. Similar to Mbps.

When copying data from a U disk or hard disk, the speed is reported in megabytes per second. Our mobile phone’s real-time display of network speed uses MB/s as its unit, too.

To clarify, what is the dissimilarity between megabits per second and megabits per second?

Here is a long preamble explaining everything. What is the distinction between megabits per second (Mbps), megabits per second (Mb/s), and megabytes per second (MB/s

First, we’ll examine the relationship between the two forms of conversion.

    ● B=Byte
    ● b=bit
    ● 1 Kb =­ 1024 bit
    ● 1 KB = 1024 Byte
    ● 1 Mb = 1024 Kb
    ● 1 MB = 1024 KB
    ● 1 Byte = 8 bit
    ● 1 MB = 8Mb
    ● 1 Mb = 0.125 MB


  1. Mbps, or Million bits per second (1,000,000bit/s), refers to a rate at which one million bits of data are sent per second.
  2. The bit is the fundamental unit of informational content in digital signals. Each bit in a binary number can only have the values 0 and 1, representing the digital information that represents the number.

The “Mb” in “Mb/s” and the “Mb” in “Mbps” both stand for “millions of bits,” so “Mbps” = “Mb/s”


  1. The files on a computer are measured in bytes, so MB stands for “million bytes.”
  2. A computer’s storage capacity is measured in bytes. As a unit of combination, the binary number string is used. Eight-bit bytes, which store a binary number with that many digits, are the most common type of byte. One bit can be either a 0 or a 1, and groups of 8 bits are called bytes (abbreviated as B)

The connection between bits and bytes will become crystal clear then:

  1. 1 byte = 8 bits
  2. Second, 1MB/s=8Mbps=8Mb/s when converting between Bytes/s and bits/s to describe the speed of a network.
  3. Currently, the theoretical capacity of a 5G network is 10Gbps, which translates to: 10÷8=1.25GB/s

Why is Mbps generally used to express network speed?

Although the network speed is typically expressed in bits/s, Mbps is the most accurate unit of network rate for telecom advertising because telecom operators are calculated according to bits when charging.

While the digital signal in transmission is typically measured as a group of 8 bits, the term “byte” only makes sense when referring to the storage of data.

The network speed unit can be written either as a Byte or a bit, but it’s important to capitalize the B when doing so.

Switching bandwidth, or Gbps, is the rate at which data can be transferred through the device at a rate of one gigabit per second (1 Gbps).

Rates in the Huawei 5G system that the US government is trying to ban are measured in gigabits per second (Gbps). To put it another way, its top theoretical speed is 10Gbps.

At present, the maximum rate that can be achieved during 5G network testing is around 900 Mbps (0.88 Gbps), and in some cases even 1.1 Gbps.

There are a few things to keep in mind when making the switch:

  ● 1B(byte)= 8 bit;
  ● 1KB(Kilobyte)=1024B;
  ● 1MB(Megabyte,)=1024KB= 1024×1024B;
  ● 1GB(Gigabyte)=1024MB;
  ● 1TB(Terabyte)=1024GB;
  ● 1PB(Petabyte)=1024TB;

Gbps * 8 = GB/s = 1024 Mbps * 8 = 1024 Mb/s

Take the following as an illustration:

  • Theoretical maximum transfer rate for USB 3.1 GEN2 is 1280 MB per second (10 Gbps = 10×1024÷8 = 1280 MB/s). A GEN2 cable is one whose data transfer rate is greater than 700 MB per second.
  • The data-transfer rate of USB 3.1 GEN1 is 5 Gbit/s, or 5×1024÷8 = 640 MB/s
