I don’t have real-time access to currency rates right now, but I can give you a quick estimate based on typical recent values.

• As a rough reference, 1,000,000,000 South Korean won (KRW) is about 700,000 to 705,000 US dollars (USD), depending on the exact current rate.
• This corresponds to an approximate rate of about 1 KRW ≈ 0.00070 USD.

For an exact amount, please use a live currency converter or check a reliable financial source right now, since rates fluctuate by the second. If you’d like, I can show you how to compute it yourself or fetch a current rate if you provide access to a live rate source.
