It's not a new mega-unit, I don't think. I've known of the kyŏng [경,
1x10^16] for as long as I've known of the cho [조, 1x10^12].

It gets even murkier when a Brit and a Yank talk about it, since they
can't agree on a billion, trillion, quadrillion, quintillion, etc.

Such a system is easier said than done (and cheaper said than done).
And I suspect that if they did change, they would lop off just one
zero, not two, keeping it much closer to the Japanese yen with which it
often dovetails and fishtails.
For now I would be satisfied with a 100,000 won bill being made. They
can even put Shin Saimdang on it.

I think someone has miscounted the zeroes/places (and I hope it's not
The article mentions an amount of 27 quadrillion won (26 billion US
In the US system, that would be 27,000,000,000,000,000 (27 followed by
15 zeroes; or, to put it more usefully, 2 followed by 16 places).
In East Asian 10,000-based numbering, that would be 2 7000 0000 0000
0000 (2 followed by 16 places).
In mathematics and science, numbers followed by multiple zeroes are
routinely written as a SINGLE DIGIT, zero through 9, and usually
followed by a decimal point and some digit(s) afterward. Thus, 2597
would be written as 2.597 x 10^3; 32,438 would be written as 3.2438 x
27 quadrillion would be written as 2.7 x 10^16 (16 being not the number
of zeroes, but the number of places following the first single
digit—the 15 zeroes and the one 7).
16 places would be the fourth power of man (as in 만/萬, not humanity,
though these numbers do represent the power of consumers). The fourth
power of man would be kyŏng:
1st power: man [만/萬] = 10,000 ^1 = 1 0000 = 10,000 (ten thousand)
2nd power: õk [억/億?] = 10,000^2 = 1 0000 0000 = 100,000,000 (hundred
3rd power: cho [조/兆] = 10,000^3 = 1 0000 0000 0000 = 1,000,000,000,000
4th power: kyŏng [경/京] = 10,000^4 = 1 0000 0000 0000 0000 =
10,000,000,000,000,000 (ten quadrillion)
27 quadrillion is 2.7 times "10 quadrillion" (1 kyŏng) so it's 2.7
But most definitely it is sixteen places following the 2.

Let's just hope they fix the currency-zero issue by the time the
economy gets to being one mole (6.02 x 10^23, give or take a few
quintillion). And there is, of course, already a Korean word for this
(used frequently at KAIST, I'm sure): 몰.
For reference, here's the original article from the Joongang Daily:
ㅡ It's getting tougher to count the zeros in talking about the Korean
macroeconomy, and some statisticians probably wish the won were worth
only 10 or 100 to the dollar instead of over 1,000. All those zeros to
describe an economy the size of Korea's has forced a new numerical term
into use: one gyeong, a unit of 10 quadrillion.
The Bank of Korea said yesterday that the sum of all transactions
through domestic financial service companies reached "2.7 gyeong won"
or 27 quadrillion won ($26 trillion) last year. Transactions in
derivatives are also more than a gyeong's worth every year.
A Bank of Korea official said that when Korea's broadly defined money
supply reached 1.3 quadrillion won, he had to refer foreign bankers to
a dictionary to confirm to them that there was such an English word as
