Scientific notation is a way of representing numbers, usually very large or very small, in the form
a*10b where 1 <= |a| < 10 is a decimal number and b is an integer (negative or positive).
a is called the mantissa and b is called the exponent.
To convert a number to scientific notation:
• If the number has no decimal point, then add one at the end.
• Then move the decimal point to just after the first digit while counting the number of places you have moved it.
• The mantissa of the new number, formed after moving the decimal point is a.
• If the original number is negative, then so is a.
• The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.
For example:
23045.06 becomes 2.304506*10^4
-23045.06 becomes -2.304506*10^4
0.00023004 becomes 2.3004*10^-4
The following are the better known metric prefices:
yotta- = septillion
zetta- = sextillion
exa- = quintillion
peta- = quadrillion
tera- = trillion
giga- = billion
mega- = million
kilo- = thousand
hecto- = hundred
deca- = ten
unit = unit
deci- = tenth
centi- = hundredth
milli- = thousandth
micro- = millionth
nano- = billionth
pico- = trillionth
femto- = quadrillionth
atto- = quintillionth
zepto- = sextillionth
yocto- = septillionth
It is: 5.8*10^9 metric tons in scientific notation
Scientific notation is scientific notation - whether it is used for metric units, Imperial units or simply for numbers.
3,582 gigabytes in Scientific Notation = 3.582 x 103 gigabytes.
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.

To convert 119 000 to engineering notation with metric prefixes, we would express it as 119 x 10^3 since 1 kilo (k) is equivalent to 10^3. Thus, in engineering notation, 119 000 would be written as 119 k.

In the SI (metric) system mass is about 3 milligrams or 0.003 grams or 3 times 10 to the negative 3 power in scientific notation. In the US system mass (weight) is 0.0000066 pounds or 6.6 times 10 to the negative 6 power in scientific notation.
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
Because exponential or scientific notation needs less digits for very large numbers and metric units are preferred because they are in multiples of 10 thus avoiding mistaken calculations.
5.008*103 km although, given the metric system, one could refer to it as 5.008 megametres!
Officially approved by the SI, no. Actually if you want such a large number, you can just as well use the base unit, and scientific notation. For example, instead of "3.2 Petahertz", you might just as well talk about 3.2 x 1015 hertz.
It is 8.9*10^-5 in scientific notation
