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

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.

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.

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.

There's a better one! Truly universally acceptable, but not being put into use anywhere (I think! )

1,0000 = Myriad

1,0000,0000 = Myllion

1,0000,0000,0000 = Byllion etc.
