How it works
- Korean counts big numbers in 만 (man, 10,000) and 억 (eok, 100,000,000). ₩100,000,000 is 1 eok, written 1억원, which is 10,000 man.
- If the won weakens by 1% against the dollar, ₩100,000,000 buys 74,326.28 USD, which is 743.27 USD less.
- That is more than 10,000 US dollars. Carrying cash or checks worth more than that into or out of Korea must be declared to customs.
