Re: Difficult question

As simple as that!
But you would have to remember
(1) A second is a billion (US) nanoseconds but not a billion (UK) nanoseconds.
and
(2) An American Gallon is different from a gallon in UK

Re: Difficult question

And a million is a thousand thousand in the UK, but a million is a hundred thousand in the US.

It.... is? 1 000 000 is a million, not 100 000.

Re: Difficult question

Rora's thinking of billions.
A UK billion is a million million and a US billion is a thousand million.
That's why there are so many more American billionaires!


Why did the vector cross the road?
It wanted to be normal.

Re: Difficult question

Richard Branson must be worth a PACKET then. LOL

I think that metric rules in this case. If you say "a billion" in a scientific journal it is assumed to be 10^9 (1,000,000,000).

Thousand, Million, Billion, Trillion, etc, each 1,000 times bigger.

Re: Difficult question

There's a better one! Truly universally acceptable, but not being put into use anywhere (I think! wink )
1,0000 = Myriad
1,0000,0000 = Myllion
1,0000,0000,0000 = Byllion etc.
