1 gb=1024 MB (mega bytes)
1 mb=1024 KB(kilobytes)
1 KB=1024 bytes
1 GB=1024*1024*1024 bytes
=1073741824 bytes
3 Gigabytes
There are 1024 Megabytes (MB) in a GigaByte (GB), and then 1024 Kilobytes(KB) in a Megabyte, and then 1024 Bytes in a Kilobyte. So in a 300GB Hard Drive, there are 300 times 1024 times 1024 times 1024 Bytes, which equals 322122547200 Bytes.
Gig is short for gigabyte. The giga prefix means one billion. Thus 3 gigs is 3 billion bytes. A megabyte is one million bytes. Thus 3 gigabytes equals 3000 megabytes.
In 1 gigabyte there are 1024 mega bytes . In 1 megabyte there are 1024 kilo bytes .3 gigabyte equals to 3 time 1024 mega bytes that is (3x1024) mega bytes.
3 GB = 3*1024*1024*1024 Bytes 3 GB = 3*1024*1024 Kilo Bytes 3 GB = 3*1024 Mega Bytes
GB, or gigabyte, is not a unit of time, but of capacity. A gigabyte is one billion bytes, according to the SI standard; or 1024^3 = 1,073,741,824 bytes, by the computing standard, where you go by powers of 2.
Computer memory comes in multiples of 2. The nearest to 1,000 that we can get with powers of 2 is 1,024..... 210... 1,024 bytes = 1 kilobyte 1,024 kilobytes = 1 megabyte 1,024 megabytes = 1 gigabyte so, 3 gigabytes = 3,072 megabytes.
when we're talking about DVD movies thinking in terms of how many bytes is pretty rediculous. a very short DVD quality movie will be measured at least in tens of mega-bytes (Mb). one megabyte is equal to 1,048,576 bytes. so, if you were, for instance, thinking in terms of how many bytes there were in a full-length DVD quality feature film then you would be talking about gigabytes(Gb). one Gb is equal to 1,073,741,824 bytes. you need between 1 and 3 gigs of space for a whole DVD worth of information.
That depends on what exactly you mean by "3gb". Because a uncapitalized "b" actually stands for bit, while a capital "B" stands for byte. In case you mean 3 gigabit (formal notation: 3 Gb or 3 Gbit): 1 gigabit equals 1,000,000,000 bits, times 3 equals 3,000,000,000 bit, divided by 8 equals 375,000,000 bytes (as 8 bits equal 1 byte). 375,000,000 equals 375 MB (megabytes). In case you actually mean 3 gigabyte (3GB), then answer is quite simple. 3 gigabytes equal 3 times 1024 megabytes: 3072 MB.
3 billion bytes or 24 billion bits.
1 kilobyte = 1024^1 = 1,024 bytes1 megabyte = 1024^2 = 1,048,576 bytes1 gigabyte = 1024^3 = 1,073,741,824 bytes1 terabyte = 1024^4 = 1,099,511,627,776 bytes1 petabyte = 1024^5 = 1,125,899,906,842,624 bytes1 exabyte = 1024^6 = 1,152,921,504,606,846,976 bytes1 zettabyte = 1024^7 = 1,180,591,620,717,411,303,424 bytesSo there are 1024^7 / 1024^3 gigabytes in a zettabyte.1024^7 / 1024^3 = 1024^4 = 1,099,511,627,776 gigabytes in a zettabyte..!If you are using the purist SI units meaning of "giga-" and "zetta-" then this would be:1000^7 / 1000^3 = 1000^4 = 1,000,000,000,000
8 bits = 1 byte, 1024 bytes = 1 Kilobyte, 1024 kilobytes = 1 megabyte, 1024 megabytes = 1 gigabyte. Or as most humans look at it 1billion bytes equals a gigabyte. 1024 gigabytes = 1 terabyte 1024 terabytes = 1 petabyte and 1024 petabytes = 1 exabyte.
