8 bits in a byte is for storage and parallel protocols. For serial protocols without a dedicated clock signal such as SATA, PCI-e, Ethernet, USB etc a byte is larger than 8 bits during transfer. 1 byte is 10 bits in 8/10 and 4/5 encoding, that really easy to work with just divide by 10 :) For other protocols 64/66 and bit stuffing, the math becomes hard.

1 Byte = 8 Bit.

Divide your Mbit/s by 8 and you'll get the MB/s.

I like the videos, but if it's in the title, it would be nice to have it in the first 30 seconds.

Good explanation, but you should have probably said that:
When you see the internet speeds in lowercase b or for example "20Mb/s" you just divide 20/8 to get the megabyte value which in this case will be 2.5 MB/s.

Back in the days of early computers for the consumer, some stores advertised a computer properly listing the RAM as 64 kilobytes and then other stores listed the computer as having 65 kilobytes.
I would think the computer advertising the one with 65 KB had more RAM but I later learned that that store was lying!
Liter I learned that hard drives was different because of formatting.

I assumed that the differece in today's hard drives was still because of formatting, but now you decribed it as that it is because they are still doing the same lies.

When dealing with consumers all measurements should be quoted in bytes per second. Marketing people like throwing bits per second because they are bigger numbers....

In casual writing the units can get ambiguous if only lowercase is used. Better stick with Mbit. The people at Fraunhofer have consistently used kBit/s with a capital B. I don't know if that is a German thing. Also bit/s always use decimal prefixes.

Dividing network speed by 10 gets a close enough approximation of the transfer rate in bytes allowing for overhead and inefficiency of the congestion avoidance mechanism.

I got a new connection and it was advertised as 10 Mbps and I was so hyped about it thinking I would get 10 mb/s download speed , guess I was wrong 😔, I'm getting like 1.4 mb/ s download speed

So in the most laymen of terms if you see 10MB u × it by 8 and that will tell u your download speed is 80 Mbps

Mb and MB is just a difference of capital, and it's so unfair that they are much more different than they look

Hi Gary. Just wondering if I'm right by saying the reason there are 8 bits to a Byte is because of the 'basic' programming? I was told that the letters were made up of dots (bits) & that each letter was a Byte! It just winds me up when network providers say they can do (this really winds me up) 'up-to' so-many 'bits' per second! Why don't they say Bytes per second? Is it to make their network look better than what it is? All the best....................

So, I thought when transferring bytes between two devices, one bit at a time, a byte was preceded by a start-bit and ended with a stop-bit. I know this is quite often used in serial communication. To convert megabits to megabytes, you would divide by 10.

When you talk about how an OS reads less bytes than a HD, if a HD is 1,000KB then wouldn't the operating system report 1,024KB, which is more not less? Thanks

i would be okay if bits/sec was completely contained to wide area networking, but when it bleeds into computer components i become a very unhappy person. i have become so frustrated with this that i am now holding the belief that bits/sec should never be used, as the vast majority of the population are more familiar with bytes. SATA 3.0 is 750MB/s, USB 3 Gen 2 is 1.25GB/s, NVME Gen 3 is 4GB/s. none of this 6Gbps, 10Gbps, 32Gbps crap.

So in theory, if I’ll get a 1 GigaBit per sec connection (let’s say both download and upload) I won’t be able to upload a video of 1GB in 1 sec, it will take 8 seconds, right? If so our connections are way slower than I thought
