What is kilo, mega, giga, tera ... ?
In the Metric mechanism there space standard methods to talk about huge and small numbers:
"kilo" because that a thousand, "mega" because that a million, and an ext ...
Example: A long rope procedures one thousand meters
It is much easier to to speak it is 1 kilometer long,
and even easier to write it under as 1 km.
You are watching: 10,000,000,000,000,000,000
So we provided kilo in prior of the word meter to make "kilometer".
And the abbreviation is "km" (k because that kilo and m because that meter, placed together).
Some an ext examples:
Example: You placed your bag ~ above a collection of scales and also it shows 2000 grams, us can contact that 2 kilograms, or simply 2 kg.
Example: Teaspoon
A teaspoon hold 5 thousandths the a liter (51000 of a liter), but it is much better to speak "5 milliliters", or create it just as 5 mL.
So, using the prefix "milli" in front of "liter" creates a brand-new word "milliliter".
Here us list the prefix for commonly used big and small numbers:
Common big and tiny Numbers
| trillion | 1,000,000,000,000 | tera | T |
| billion | 1,000,000,000 | giga | G |
| million | 1,000,000 | mega | M |
| thousand | 1,000 | kilo | k |
| hundred | 100 | hecto | h |
| ten | 10 | deka | da |
| unit | 1 | ||
| tenth | 0.1 | deci | d |
| hundredth | 0.01 | centi | c |
| thousandth | 0.001 | milli | m |
| millionth | 0.000 001 | micro | µ |
| billionth | 0.000 000 001 | nano | n |
| trillionth | 0.000 000 000 001 | pico | p |
Just remember for big values (each one a thousand times bigger):
"kilo mega giga tera"
and for little values (each one a thousand time smaller):
"milli micro nano pico"

How large Are They?
There is a many difference in between them. Think in regards to time:
A longer list:
A thousand secs is around a quarter of one hour A million secs is about 12 days A billion secs is around 32 years, practically half a lifetime A trillion seconds is about 32,000 years (the last Ice period finished 12,000 years ago)Much Bigger and Smaller
There are likewise prefixes for lot bigger and also smaller numbers:

| Novemdecillion | 1060 | |
| Vigintillion | 1063 | 1 followed by 63 zeros! |
And a Googol is 1 complied with by one hundred zeros (10100) :
10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
Then there is the Googolplex. That is 1 complied with by Googol zeros. I can"t also write down the number, due to the fact that there is not enough matter in the world to kind all the zeros:
10,000,000,000,000,000,000,000,000,000,000, ... (Googol number of Zeros)
And a Googolplexian is a 1 complied with by Googolplex zeros. Wow.
