Mbps vs. MBps: Understanding the Difference in Internet Speed Measurements


Discover the dissimilarity between Mbps and MBps in measuring internet speed. This article clarifies the distinction, helping you make informed decisions about your internet connection.

100Mbps = 12.5MBps

In today's digital age, where the internet plays an integral role in our daily lives, it is important to understand the different units of measurement used to quantify internet speed. Two common terms that often cause confusion among users are Mbps and MBps. While they may seem similar, they actually represent different measurements and understanding the distinction is essential in evaluating internet speeds accurately.

What is Mbps ?

Mbps, which stands for Megabits Per Second, is a measurement of data transfer speed. It quantifies the amount of data that can be transmitted over a network in a second. The prefix "mega" denotes one million, and a bit represents the smallest unit of digital information. Mbps is commonly used to measure internet connection speeds provided by Internet Service Providers (ISPs). For example, if your internet plan has a download speed of 100 Mbps, it means you can theoretically download 100 Megabits of data per second.

What is MBps ?

On the other hand, MBps, which stands for Megabytes Per Second, measures the actual data transfer rate in terms of file size. A megabyte is larger than a Megabit, as it consists of eight Megabits. It is important to note that the lowercase 'b' in Mbps and MBps denotes bits and bytes, respectively. Bytes are used to measure file sizes and data storage, while bits are used to measure data transfer speeds.

The difference between Mbps and MBps

To understand the practical implications of the difference, let's consider an example. Suppose you have an internet connection with a download speed of 100 Mbps. In this scenario, you would expect a maximum download speed of approximately 12.5 Megabytes per second (100 Mbps รท 8 = 12.5 MBps). This means that if you were downloading a file, the speed at which it would be transferred to your device would be around 12.5 Megabytes per second.

In summary, having a consistent speed of 100 Mbps will enable us to transfer the following amount of data (in Megabyte) within the mentioned time frames.

  • Within one Second - 12.5 MB of data can be transferred.
  • Within one Minute - 750 MB of data can be transferred.
  • Within one Hour - 45,000 MB of data can be transferred.
  • Within one Day - 1,080,000 MB of data can be transferred.

Here are the common Broad band speeds offered by some of the ISPs, and the equivalent value in MBps.

Speed in Mbpsin MB Per Second
100 Mbps 12.5 MBps
200 Mbps 25 MBps
500 Mbps 62.5 MBps
750 Mbps 93.75 MBps
1,000 Mbps 125 MBps

It's important to be mindful of this distinction when comparing internet speeds, as ISPs typically advertise their plans using Mbps, while file download speeds are often represented in MBps. This can lead to confusion and unrealistic expectations if the units are not properly understood. For instance, if you are downloading a file at 1 MBps (megabyte per second), it does not necessarily mean you have a 1 Mbps (Megabit per second) internet connection. The actual internet speed required to achieve that download speed would be approximately 8 Mbps.

Understanding the difference between Mbps and MBps is crucial in assessing your internet needs and making informed decisions when choosing an internet service provider. Factors such as streaming high-definition videos, online gaming, or transferring large files all require different levels of bandwidth. Mbps is commonly used to measure internet speeds because it focuses on the speed of data transmission, which is vital for real-time activities such as video conferencing and online gaming. On the other hand, MBps is more relevant for tasks involving file downloads or data storage, where the size of the files being transferred matters.


In summary, Mbps and MBps represent distinct measurements when it comes to internet speed. Mbps quantifies data transfer speeds, while MBps measures the actual data transfer rate in terms of file size. Being aware of this disparity enables users to better comprehend their internet speeds and make more informed choices when it comes to their internet service plans. By understanding the difference between Mbps and MBps, users can ensure they have the necessary bandwidth for their online activities and avoid confusion surrounding internet speed measurements.
