This is because you have to multiply by 1024 each time instead of 1000. These binary equivalents go up in multiples of 2 10 and they become increasingly distant from their SI equivalents as they get larger. 2 10 (1024) approximates 10 3 (1000) and this is what the kibibyte is and is close in value to the kilobyte. This is because computers use binary and some measures still use these powers of two. The orange and green units at the bottom use binary multiples. standard SI prefix + either bit or byte). These are standard SI prefixes for the familiar powers of ten that increment by three powers (i.e. The powers of ten appear in the rightmost column. The blue and yellow boxes at the top are the SI standard units and they use base 10. Data storage is usually quoted in terabytes and computer memory (RAM) in gigabytes. Very high data transfer rates are possible with optical fibre and this is the proposed technology for Australia's National Broadband Network ( NBN). A connection speed of 8 megabits per second is equivalent to one megabyte per second. Connection speeds are usually quoted in megabits per sec (Mbps) but most of us are familiar with megabytes (MBs). Converting between the various information units is very important when evaluating internet speeds and data (traffic) allowances. For example, 1 kilobit can hpossible states (or more than 1 followed by 301 zeros). Before long the number of possible states becomes unmanageable large. Since each bit can have two states, the total number of states in a byte is 2x2x2x2x2x2x2x2 or 2 8 or 256 states. A bit can have two states (0 or 1) and is the basis of binary computing. Units of data are based on bits ( binary dig its). Units below use binary multiples and are slightly different from the SI units above. Sample task: convert 512 megabytes to gigabytes (SI).Data Units Converter: bits, kilobits, megabits, bytes, kilobytes, megabytes, gigabytes by Russell Kightley MediaĬonvert Data Units: Bits & Bytes Calculator Sample task: convert 512 megabytes to gigabytes (binary, also MiB to GiB). Below you can see two conversions examples, one using the binary and one using the decimal (SI) standard. #Kb mb gb calculator how toHow to convert MegaBytes to GigaBytesĬonverting Megabytes to Gigabytes is fairly straightforward, once you settle on a definition of the MB and GB. If you disk drive has 2 TiB capacity, then it will contain exactly 2048 MiB or 2048 MB as reported by your OS. If you are using the size in megabytes as reported by your operating system, then they are most likely in proper binary metrics, 2048 MB would be 2,147,483,648 Bytes, or you would require about 7% more storage in SI gigabytes. If your disk size is in SI units, then 2TB = 2,000,000,000 Bytes which is less than 2048 MB (SI), which are equal to 2,048,000,000 Bytes. Most disk drives are marketed using the SI standard, so 2TB will contain only 2000 MB, or less, depending on your MB definition, so you will not be able to fit the data. #Kb mb gb calculator portableFor example, if you know you need to store 2048 MB and you have a 2TB portable disk drive, will you be able to fit them on it? Conversion is often necessary when the capacity of the storage you are considering is expressed in a metric different than the one you are calculating the size in. The difference is in the capacity they denote. Difference between MB and GBīoth the megabyte and the gigabyte are measures of data stored in a digital medium. In our MB to GB converter you can flip a checkbox to use the SI standard for the megabyte, depending on your needs. The SI also defines a new metric - GibiByte (GiB) that is equal to 1024 MB.Ĭare should be taken that the definition you use is the same as anyone you communicate it with. According to the established binary definition there are 1024 MB in a Gigabyte, while under the SI definition there are 1000 MB in a GigaByte. There are two competing definitions of the GigaByte.
