The WWI cases
Write 10 Gaga grams in scientific notation and convert the answer into imperial unites
1 x 10^10 grammes. 10 gigagrammes équivaut à environ 352 739 619,52 onces impériales.
A billion - 109.
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.
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.

100 gigabytes
A gigA-gram would be one billion grams, or one million kilograms.
Engineering notation is similar to scientific notation, with the constraint that the power of ten must be a multiple of 3 (or -3) or zero. Example: 1. x 102 = 100. x 100 The advantage of engineering notation, is that moving between different metric prefixes (such as kilo-, mega-, giga-, milli-, micro-, nano-) is easier, because they change by a factor of 103. So in the example above with 1. x 102, if the units were megawatts, and you wanted to see how many kilowatts that was, it is easier with Engineering Notation than scientific. 100. x 100 megawatts = 100. x 103 kilowatts
If you want to write Giga in standard form you put it as x109. So if you wanted to convert 2GV to volts it would be 2x109 V.
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.
Giga-tronics Incorporated (GIGA) had its IPO in 1983.
