Megabits vs. Megabytes: Here'southward How They're Different
Jun eighteen, 2021 Share
FAQ, Technology
There are a lot of confusing technical terms when working with computers and the internet, simply few are as needlessly cryptic every bit the deviation between megabits per second (Mbps) and megabytes per 2nd (MBps). The two terms audio nearly identical when spoken and are abbreviated with the verbal same messages . The only departure is the capitalized "b" in the latter term .
Unsurprisingly, the two terms go mixed up all the time. Fifty-fifty people who sympathize them perfectly can bungle the ii with a slip of the tongue or typing the wrong "b."
We'll explain what the departure is so you can keep them straight when it really counts.

$.25 vs. bytes: What is the difference?
The term chip is short for binary digit, and it'due south the smallest unit of information. The value is either a "1" or a "0" although the value can signify "on" and "off" states or something like.
The term byte is a group of 8 $.25. This term is likewise used to draw the smallest unit of memory and storage.
Any measurement written in bytes is eight times larger than the corresponding unit measured in bits. In other words, i megabyte (ane MB) = viii megabits (8 Mb). And 1 gigabyte (1 GB) = eight gigabits (8 Gb).
With us so far?
What does Mbps mean?
Bits per second (bps) is the number of bits that can motility between two devices in a single second. When talking most cyberspace speed, this is the number of bits that arrive on your automobile every 2d. Information technology's also sometimes called your download speed or your bandwidth.
Bits per 2d can also have metric prefixes. One kilobit per second (kbps) is 1,000 bps, i megabit per second (Mbps) is ane,000,000 $.25 per 2nd, and 1 gigabit per second (Gbps) is 1,000,000,000 bits per 2d.
You lot could technically measure speed in bytes per second equally well, simply by taking the speed in bits per second and dividing past eight. However, speed is most never measured in bytes, so if you see a speed listed for an internet connection, it's safe to say that it'southward using $.25 per second.
What are bits and bytes used for?
We tend to use the terms "bits" and "bytes" in different settings. Both terms describe a measurement in size, but the term "bit" is also used to measure out speed.
Bytes
In terms of retention, a byte is the smallest storage slot. Your hard drives, SSDs, USB sticks, and system retention are e'er measured in bytes.
Software is measured in bytes too. A single byte is just large enough to store the information for one standard grapheme, so storing the give-and-take "hello" would need five bytes of memory, one for each letter of the alphabet. This is why computer retention is generally measured in bytes.
$.25
A bit is used to make up one's mind your internet speed, but measuring data in motion (downloading and streaming) is trickier than measuring data at residuum (files, programs, etc.).
For example, the websites you visit and the emails yous send are cleaved up into packets and sent in several different directions, often arriving at your computer out of order that must exist rearranged. This erratic catamenia of data isn't always like shooting fish in a barrel to divide into bytes, so the speed at which data moves is ordinarily measured using bits per second.
When someone talks about data transfer rates, upload speeds, download speeds, or bandwidth, they're probably measuring it in bits per second (bps).
Megabits vs. megabytes: Why it matters
These subtle differences in units make it easy to flub your math when dealing with your internet speed. If you happen to become them mixed up, your calculations will be off. Way off.
For instance, let'due south say you want to download a 500 MB file, and you take a 100 Mbps net connectedness. If you don't discover the capital letter B in the file size, you might estimate that this download would take five seconds. However, the units don't lucifer up. The file size is measured in megabytes, while the connection speed is measured in mega$.25 per second. Since the file size is eight times larger than you originally estimated, it actually takes eight times every bit long to download—40 seconds.
Now, waiting 35 seconds longer than you lot expected isn't too bad, but waiting an extra 35 minutes on a download that was supposed to have only five is more than of an inconvenience. This can also be frustrating if you realize you're paying for an internet connection that gives you a lot less speed than you thought.
Megabits vs. megabytes: Why it doesn't affair
If you lot're having trouble keeping rails of all these numbers, relax. Take a deep jiff, and get yourself a snack. While information technology's important to know the difference between bits and bytes (and to know that there is a departure), you lot don't accept to worry well-nigh making an expensive blunder.
First, bits and bytes are used in different contexts. Generally speaking, speed e'er uses bits and storage capacity always uses bytes. If you lot're buying a hard drive, all the brands yous're comparison will exist using bytes. If you're looking for an internet provider, all the speeds will use $.25.
You never accept to worry well-nigh converting betwixt units. Even if a provider wanted to be sneaky and measure out its speed in MBps instead of the standard Mbps, it would only make their connection look eight times slower than it actually is.
2nd, you'll likely never take a practical need to calculate exact download times. When you exercise download a large file, whatsoever modern browser will summate the download time for you automatically. Merely fifty-fifty these exact calculations are rarely spot-on because there are and then many other factors that touch on how long it takes your data packets to download.
Pro tip:
Even the exact size of a megabyte isn't always exact . For instance, Microsoft Windows still defines "kilobyte" equally 1,024 bytes (2 20 ) and "megabyte" as i,024 kilobytes, although the proper terms are "kibibyte" and "gibibyte."
Lesser line
Megabits per second (Mbps) is a measure of data speed. Megabytes (MB) is a measure of data book. Bytes are fabricated up of 8 bits, so to convert a value in bits to bytes (or Mbps to MBps, Gbps to GBps, etc.), simply divide the value past eight.
Knowing the difference between bits and bytes is useful for navigating discussions near internet engineering science and other digital devices. It can also help y'all ask more useful questions when dealing with tech support or customer service.
Fortunately, in this instance, knowing is significantly more than half the battle. Situations where you have to really exercise the math rarely popular up outside of a computer science quiz. But now that yous can do the math if you need to, get ready to astonish your friends next time this category pops upwards on Jeopardy!
