epangoMB=Mo=1,000,000 bytes (o). So, if you have bytes and you want to convert them to MB, you divide by 1,000,000. Conversely, if you have MB and you want to convert them to bytes, you multiply by 1,000,000.
I hope you understood. -
epangoHello,
"In fact, a bit is a bit like a sentence that contains 8 words, and here the words are 8 bytes:
So 1 bit = 8 bytes ....".
And no! Bit is the acronym for binary digit, formed from the b of binary and the it of digit. 1 bit is a binary element, 0 or 1.
Byte (English word) = byte, that is, 8 bits.
The confusion comes from the fact that the symbol for byte should be B, but some use b which is the abbreviation for bit. So:
1B (byte) = 1 octet (o) = 8 bits.
1MB = 1 Mo
Thus a FireWire port with a speed of 800 Mbps (800 megabits per second) = 800:8 = 100 Mo/s (100 mega-bytes per second).
So when the value is given in Mbits (like the speed indicated by the ISP), it must be divided by 8 to get the value in Mo or MB.
It's the opposite of what is said by epithenium.
Sincerely.-

JuanitoHello,
just a little clarification, a byte is not equal to an octet.
The byte is the number of bits in a memory range which therefore depends on the processor architecture (there are processors where the byte is worth 7 bits or 9 bits) while an octet (as its name indicates) is automatically 8 bits.
Peace -
BytoubitIt is also a problem of spelling and writing. Spelling: One must not confuse a byte, a bit, and an octet. A Byte is a set of 7, 8, or 9 bits. An octet is a set of 8 bits. If we compare it to euro, 1 bit = 1 € gram, an octet = 8 € 1 Byte = 7, 8, or 9 €. 1 kilobit = 1000 € and 1 ko = 1000 octets and 1 kilo € = 1000 € then, like for all units, we multiply by 1,000 to get millions (mega), billions (giga), etc. So 1 Byte is roughly = to 1 octet which is approximately 8 bits depending on the case. 1Kbps = 1 KB, 1,000 B whereas 1Kb = 1000 bits. 1Mbps = 1000 KB 1 Mb = 1000 Kb
Writing Bit is written in lowercase b while Byte is written in uppercase B. Kilo = K Mega = M Giga = G etc. Above that it goes too fast, there’s no time to count! -
epango"It is also a problem of spelling and writing. Spelling: One must not confuse a byte with a bit and an octet. A byte is a collection of 7, 8, or 9 bits. An octet is a collection of 8 bits."
It has already been said.
"If we compare with the euro, 1 bit = 1 € gr, an octet = 8 € 1 Byte = 7, 8, or 9 €. 1 kilobit = 1000 €"
You need to remember the basic rules of equality. Writing 1kb=1000€ is an attack against mathematics. -

epitheniumHello,
Be careful not to confuse MB and Mb ...
MB and Mb are generally different... (but sometimes some people make the mistake)
MB = Mega-bytes = Mega-octets
On the other hand, Mb = Mega-bit, and is different from the Mega-octet.
In fact, a bit is a bit like a sentence that has 8 words, and here the words are 8 octets:
So 1 bit = 8 octets ....
1000 MB = 1000 Mo
1000 Mb = 8000 Mo
And mega-bits and mega-bytes are not pronounced the same way.
That was just a small clarification... -
epitheniumYes, that's right...
I messed up, that's what I meant to say but I was a bit too quick, I didn't proofread my post... and I got it mixed up. -

sebsauvage ModeratorIn the article, he made a huge mistake: the unit of mass is not the gram, but, strictly speaking, the kilogram.
No, the unit is indeed the gram. :-)
The reference is the kilogram, but the unit remains the gram. -
epangoHello,
"No, the unit is indeed the gram. :-)
The reference is the kilogram, but the unit remains the gram
We even teach middle school children that the unit of mass is the kilogram. Look in a 5th-grade physics and chemistry book.
Here's a link that will not only confirm that it is indeed the kilogram, but also provide you with the history of this unit that has French origins:

sebsauvage ModeratorMb = Mega-bytes = Mo = Méga-octets
Mb is English, Mo is French but they measure the same thing.
So 1000 Mb = 1000 Mo.

yuiLa différence entre Mo et Go est la suivante :
- Mo signifie Mégaoctet, qui équivaut à 1 024 Ko (kilooctets) ou 1 048 576 octets.
- Go signifie Gigaoctet, qui équivaut à 1 024 Mo ou 1 073 741 824 octets.-

epangoDid you read what he wrote? I don't think so. He wrote:
1GB=1000MB.
I remind you that the multiplier prefix giga has the symbol G and not g. Similarly, mega has the symbol M and not m. If upper and lower case didn't matter, you would write:
1MV=1mV and why not 1MV=1mv?
You're capable of understanding that, right! -

epangoHello,
In the article, he made a huge mistake: the unit of mass is not the gram, but, strictly speaking, the kilogram. He should have chosen another example than mass, such as the unit of length: meter and kilometer. We do not use the multiplicative prefix kilo (x1000) for the unit of mass, as kilo-kilogram sounds odd. That's why we use the tonne for 1000 kilograms.
Best regards.

sebsauvage ModeratorMy apologies.

You are right.
Originally, it was indeed the gram, but in 1875 the kilogram was chosen as the unit of mass instead of the gram for various reasons (political, it seems).
I will correct my article. -
sebsauvage ModeratorThe article on my site has been corrected.

epangoHi,
Your question is too vague. What do you really want to know?
See you soon

ryan92I stop you right there; based on your calculations, what you explain is not the concrete truth since 1 byte = 8 bits, so when we have a 100 mbits connection, it equals 12.5 MB (100 mbits / 8 = 12.5 MB/s) maximum. But like in any network, this is a theoretical speed. So far, I've had fiber optic for two years, and personally, the maximum speed I've been able to reach is 11.9 MB/s.
P.S.: One must not confuse bits, which correspond to the base of the European computing unit, and bytes, which are the American representation of octets.
1 byte = 8 bits-

Who are you responding to? No one said otherwise. Besides, no one mentioned the network connection speeds here.
"One must not confuse bits which correspond to the basis of European computing units and American bytes which correspond to octets."
But no, the bit is not fundamentally the European computing unit. As I said, bit is an acronym formed from binary digit. It was the Americans who invented it. Lastly, before intervening in a discussion, one must read what has already been said. Do not confuse bit and byte: this has already been stated in 2006, even if not in strictly identical terms. -
