Why do you have scientific notation?
Scientific notation makes it easier to express numbers of extremely small or large magnitude. For example, we could either say that something is .00000000068 meters long, or simply use scientific notation to write it as 6.8 x 10-10 meters. There is also an "engineering" notation which is similar to scientific notation, but all exponents are multiples of 3. This is so we can introduce prefixes such as nano, micro, kilo, giga, etc. The number 573000 would be written as 5.73 x 105 in scientific notation, and 573 x 103 in engineering notation.
Is a megabyte the largest unit of measurement?
For measuring computer storage (memory), both gigabyte and terabyte are larger. See related link for more prefixes. Note that there has been some confusion with using the 'metric' prefixes with memory. Originally, a kilobyte was 1024 bytes (not 1000), and a megabyte was (1024 x 1024 = 1048,576 bytes)
Why do you use engineering notation in electronics rather than scientific notation?
Sometimes engineers use either scientific or engineering notation, although you are correct that most of the time engineering notation is used. The reason for this the use if greek letter prefixes for quantities. Very often large and small quantities are expressed as micro, mega, giga, nano, and so on. These terms relate to engineering notation in multiples of 1000 or 1/1000. It is a very convenient shorthand not only in writing but also while speaking.Read more: Why_in_engineering_you_use_engineering_notation_instead_of_scientific_notation
What is scientific and engineering notation?
Scientific notation is normally used for numbers that are either far to large or far to small to be written conveniently in decimal notation.A,BFor example the Earth's mass is approximately: 5,973,600,000,000,000,000,000,000.0 kgIn scientific notation this would be written as:5.9736 x 1024 kg.In normalised scientific notation numbers are written in the form:A,Ba x 10nWhere:a is a number between 1 and 10n is a positive or negative whole number.In engineering notation, the n value is commonly in the form of multiples of 3. In this way the number will always explicitly match the corresponding SI prefixes.BFor example a distance of 50,000 m would be written as:Scientific Notation: 5 x 104 mEngineering notation: 50 x 103 mIn this example 103 corresponds to the SI prefix "kilo"C as such the engineering notation could be directly described verbally as "fifty kilometres" whereas scientific notation yields the much more unwieldy "five times ten to the power four metres" which is much less intuitively easy to understand, even though it is exactly the same distance.Guidance on converting to and from scientific notation is given in the related links.

How a GB of data looks compared to a TB of data?
Check your metric system unit multiplier prefixes. Giga- (G) means 1E9 in scientific notation. Tera- (T) means 1E12 in scientific notation.A GB is thus 1/1000th of a TB.This is analogous to these examples:a meter is 1/1000th of a kilometerthe height of a person 5 feet 3.36 inches tall is 1/1000th of a milea penny is 1/1000th of $10two pounds is 1/1000th of a tonetc.
What is a gigadollar?
In the USA, a giga-something is 1 billion of something, for example, a gigabyte is 1 billion bytes. Similarly, a gigadollar is 1 billion dollars. Most elsewhere, a US billion is called a miljard, and a billion is a US trillion. To avoid confusion, use the metrix prefixes like kilo-, mega-, giga-, tera-, etc. or scientific notation, e.g. 1 gigadollar is 1e9 USD.
Is 2 gigabytes more than 256 megabytes of ram?
No Mb is megabyte is million bytes,Gb is gigabytes is billion bytes, one thousand times as big as Mb(to be stringent for prefixes in scientific notation: m (lowercase m) is milli which is thousandths (1/1000) M (upper case) is Mega = million)there is no prefix g (lower case)

How many gigabyte in kilobyte?
It's the other way around. Kilobytes go into Gigabytes One million KB's goes into one GB. 1 gigabyte = 1 048 576 kilobytes
What is the biggest unit than joule?
In SI, if a unit is too small or too big, either standard prefixes or scientific notation is used. Standard prefixes would be, for example, kilojoule (a thousand Joule), megajoule (a million Joule), gigagoule (a billion Joule) etc. But if you want to indicate the power output of the Sun for example, the numbers are so enormous that it doesn't make sense to use special prefixes; scientific notation is much clearer in this case (3.83 x 1026 Watt or Joules/second).
Is a megabyte the largest unit of measurement?
For measuring computer storage (memory), both gigabyte and terabyte are larger. See related link for more prefixes. Note that there has been some confusion with using the 'metric' prefixes with memory. Originally, a kilobyte was 1024 bytes (not 1000), and a megabyte was (1024 x 1024 = 1048,576 bytes)
How much mb is 0.5 GB?
approx 100mb In the context of computers, the prefixes K, M, G and T work on powers of 1024, not 1000. 1GB = 1024MB, so 0.1GB ≈ 102MB.
