A trillion in the U.S is how many in the U.K?

1 Billion.

Brits are strange.

What we call 1 Billion, they call one Thousand-Million.

Likewise, for them ...

10,000,000,000 is Ten-Thousand Million;
100,000,000,000 is One-Hundred-Thousand Million;
1,000,000,000,000 is One Billion.

They don't use the word Trillion (and even think we're very silly for inventing it); they just keep going with Billions.

10^13 = 10 Billion (our 10 Trillion)
10^14 = 100 Billion
10^15 = 1000 Billion (our 1 Quadrillion)
10^16 = 10,000 Billion
10^17 = 100,000 Billion
10^18 = Million Billion (our 1 Quintillion)
10^19 = 10 Million Billion
10^20 = 100 Million Billion
10^21 = 1 Billion Billion (our 1 Sextillion)
10^22 = 10 Billion Billion
10^23 = 100 Billion Billion
10^24 = 1000 Billion Billion (our 1 Septillion)
10^25 = 10,000 Billion Billion
10^26 = 100,000 Billion Billion
10^27 = 1 Million Billion Billion (our 1 Octillion)

and so on.

it how much David Beckman got paid.

But seriously, they are now the same.

To quote wikipedia:

For most of the 19th and 20th centuries, the United Kingdom uniformly used the long scale,[2] while the United States of America used the short scale,[2] so that usage of the two systems was often referred to as "British" and "American" respectively. In 1974 the government of the UK abandoned the long scale, so that the UK now exclusively applies the short scale interpretation in mass media and official usage.[3][4][5] Although some residual usage of the long scale continues in the UK, the phrases "British usage" and "American usage" are no longer accurate or helpful characterizations. The two systems can be a subject of misunderstanding controversy and can arouse emotion. Usage changes can evoke resentment in adherents to the older system, while national differences of any kind can acquire patriotic overtones. [6]

In the old days, when I was at school in England in the '50s

Million=10^6
Billion=10^12
Trillion=10^18

but fashions have changed. To avoid ambiguity I stick with the numerical convention, using superscripts if the font permits it, or the programming convention, as on the rhs of the equations above.

One way to remember the British system is to take the prefix's value (trillion = tri = 3) and multiply it by 6, and that's the number of zeros past the 1. 1 trillion = 1 with 3 * 6 zeros = 1x10^18. Unfortunately, the rule breaks down for million, since the prefix is "mi" = ?? Well, just have to remember that mi = 1, I suppose.

Thousand: 10^3 = 1,000

Million: 10^6 = 1,000,000

Billion: 10^9 = 1,000,000,000

Trillion: 10^12 = 1,000,000,000,000
