Million, Billion, Trillion


What’s the difference between one million, one billion, and one trillion?


A million seconds is 13 days.
A billion seconds is 31 years.
A trillion seconds is 31,688 years.

A million minutes ago was – 1 year, 329 days, 10 hours and 40 minutes ago.
A billion minutes ago was just after the time of Christ.

A million hours ago was in 1885.
A billion hours ago man had not yet walked on earth.

A million dollars ago was five (5) seconds ago at the U.S. Treasury.
A billion dollars ago was late yesterday afternoon at the U.S. Treasury.

A trillion dollars is so large a number that only politicians
can use the term in conversation… probably because they
seldom think about what they are really saying. I’ve read that
mathematicians do not even use the term trillion!
Here is some perspective on TRILLION:

Trillion = 1,000,000,000,000.
Western civilization has not been around a trillion seconds.
One trillion seconds ago – 31,688 years – Neanderthals stalked the plains of Europe.

Million: 1,000,000
Billion: 1,000,000,000
Trillion: 1,000,000,000,000
Quintillion: 1,000,000,000,000,000,000
Sextillion: 1,000,000,000,000,000,000,000
Nonillion: 1,000,000,000,000,000,000,000,000,000,000
Centillion: 1 followed by 303 zeros

I just calculated and I have roughly three nonillion things to do this week ;-)

Take care,

    What’s really weird is that in spanish is different.

    “Un millon” = One Million = 1,000,000
    “Un billón” = One Million millions = a thousand billions = a trillion = 1,000,000,000,000

    Think it like: a thousand thousands is a million, so a million millions is a billion… and I guess it goes like that for trillions and so on (in spanish).

    Or at least that’s what every spanish speaking person I’ve met (me included) says.
