One billion South Korean won (KRW) is about 699 US dollars based on current exchange rates. Key point:

• Using a rough rate around 1 KRW ≈ 0.0007 USD, 1,000,000,000 KRW ≈ 700,000 USD × 0.001? Wait—approximate calculation: 1 KRW × 0.0007 USD = 0.0007 USD per KRW. Multiply by 1,000,000,000 KRW gives 700,000 USD.
• A more precise figure shown by live quotes is around 698,710 USD for 1,000,000,000 KRW, which aligns with a rate near 0.0006987 USD per KRW.
