![]() The size is typically given in MB, GB, TB, or PB as conventionally understood. In most cases the file size will be visible either in the download interface, or in the file system manager that you are using (e.g. The download size may vary from several megabytes to gigabytes to terabytes or petabytes. connection bandwidth) as well as the size of the file or files that are to be downloaded or uploaded. To use the calculator and esimate the required time for a download or upload, as well as the download ETA, two parameters need to be known: the internet speed (a.k.a. Does it matter what type of file(s) are being downloaded?.Why my downloads take a longer than the estimated time?.Sorry for all the math, but it is impossible to explain how this all works without it! Surprisingly, most people never noticed or recognized that the internet provider’s measurements are different from hard drive read and write speeds. Hopefully, now you have a much better idea of the difference between megabits and megabytes. Fiber-optic internet at 940 Mbps converts to 117.5 MBps, which is almost 118 megabytes per second.Cable internet at 2000 Mbps converts to 250 MBps.DSL at 45 Mbps converts to just 5.625 MBps, which is under 6 megabytes per second.Translating the above internet speeds from Mbps to MBps, you get the following calculations: However, it illustrates the difference between DSL, cable internet, and fiber-optic internet using the industry-standard Mbps. The speeds above are for reference only, and you are not guaranteed to get those measurements. Fiber-optic connections allow up to 940 Mbps.Cable connections allow up to 2000 Mbps.Digital Subscriber Line (DSL) connections allow up to 45 Mbps.Here are a few examples of broadband types and the maximum speeds they advertise. It is best to get as fast a connection as possible in your area within your given budget, but be sure to calculate the provider’s true speed potential by converting to Mbps to MBps speeds. Therefore, the Mbps system sounds better than the MBps system. If you are a heavy internet user, faster speeds are more desirable. The “Need for Speed” Motivates Mbps Advertising The vast majority of Internet Service Providers (ISPs) will advertise their speeds in Mbps, which is the megabits per second measurement. Internet Service Providers use Mbps rather than MBpsįortunately, the only time you really need to know the difference between a megabit and a megabyte is when you are shopping for a new broadband package. A fiber-optic internet package at 50 Mbps sounds much faster than 6.25 MBps, which is what the transfer speed “actually” is when measured in megabytes instead of megabits per second. add a third integer to make things look cheaper, such as $2.099 instead of $2.10. In this situation, the SAE industry is set in their ways, just like the Mbps and MBps controversy.Īside from different industries, the Mbps measurement scale makes things seem faster than they really are. Still, The US uses the Society of Automotive Engineers (S.A.E.) scale, also known as SAE, in addition to the metric (meters) system even though metric is the industry’s universal standard. In comparison to Mbps and MBps, most of the world uses the metric system for size measurements. It has nothing to do with the ISPs but the relative areas of the appropriate industries. Why can’t companies use just megabytes to describe both speed and size? The simple answer is that the two areas of technology evolved separately, and both are so entrenched in their way of doing things that it is almost impossible to change. Why We Use Megabits and Megabytes Instead of One Measurement ![]() Google has a helpful Mbps and MBps converter tool to make calculations simple. To confuse matters more, a megabit and a megabyte are not the same size. Those last two points are quite important as they mean very different things. The measurement is the same, whether you refer to storage devices or file transfers. A megabyte is used to measure file size.A megabit is used to measure download and upload speeds.Here are the bare essentials of what you should know: Understanding Mbps helps you make an informed decision when shopping for internet service and for calculating what speed you need based on your typical uses. Internet speeds usually get advertised in megabits per second (Mbps), so it pays to know what the term means and how much data one megabit contains. The difference in speed scales is mainly technical, but it has a bearing when making broadband buying decisions.
