Hella vs Giga

Hella is a proposed SI (International System of Units) prefix for 1027 (10 raised to the 27th power). Giga is the actual SI prefix for 109 (10 raised to the 9th power).

 

International System of Units (SI) Prefixes

Factor Name Symbol Long Format
101 deka da 10
102 hecto h 100
103 kilo k 1.000
106 mega M 1,000,000
109 giga G 1,000,000,000
1012 tera T 1,000,000,000,000
1015 peta P 1,000,000,000,000,000
1018 exa e 1,000,000,000,000,000,000
1021 zeta Z 1,000,000,000,000,000,000,000
1024 yotta Y 1,000,000,000,000,000,000,000,000
1027 hella*   1,000,000,000,000,000,000,000,000,000
 
*hella is only a proposed SI prefix
 

Examples

  • Take a typical 6 character bit.ly url http://bit.ly/9xoCS (though they can keep expanding). Assume that they only use ASCII numbers, capital, and miniscule letters, so a-z, A-Z, and 0-9 (that's 626). Then, with the six character variation, bit.ly can create 56.8 gigaurls, or 5.68e-17 hellaurls.

    How long would a bit.ly URL have to be to be able to create at least one hellaurl? You would only need an 18 character URL path (past domain name), 6218. So, http://bit.ly/9xoCS26wumy79d0v3K, which would be 47.67 hellaurls.
     
  • The amount of energy released by the sun is about 0.3 hellawatts of energy[1], or about 300,000,000,000,000,000 gigawatts.

  • Hella is not so big after all if you consider that there are about 1047 possible moves in chess[2], or roughly 100,000,000,000,000,000,000 hellamoves. Add 18 more zeros to figure out the gigamoves yourself.

  • There are about 177,278,861,500 gigagallons in the Pacific Ocean (161,000,000 miles3 * 1.10111715 X 1012 US gallons/mile3), so there are about .0000001722 hellagallons.

  • Light travels about 0.3 gigameters per second. Add 18 zeros before the 3 to get it in hellameters.
     
  • If you take Google Map's recommended route across I-80, there are about 2906 miles to travel from San Francisco to New York City. That is about 184.1 million inches, or a mere 0.1841 gigainches from San Francisco to New York, so about 0.0000000000000000001841 hellainches.



     
  • Odds of winning the jackpot in Superenalotto in Italy
    • 1 in 622 megachances
    • 1 in 0.62 gigachances
    • 1 in a snowball 0.00000000000000000062 hellachances
       
  • The 2010 New York Yankee's payroll is about .206 gigadollars [3] ($206 million). Add 18 zeros before the 2 to get the helladollars.

  • There are about 6.8 billion people on the Earth, so that means there are 6.8 gigapeople, or 0.0000000000000000068 hellapeople.
     
  • There are about 31.5 million seconds in a year, so that means there are 0.0315 gigaseconds, or 0.0000000000000000000315 hellaseconds.
     
  • There are about 1024 stars in the universe[6]. That is 1015 gigastars, or  .001 hellastars.
     
  • There are about 1080 atoms in the universe. That is 1071 gigaatoms, or 1053 hellatoms.
