About the South Korean Won

The South Korean Won uses the ISO code KRW. Whether you price products, settle invoices or show a live converter, the Rate-API exposes KRW against 160+ currencies updated hourly.

Convert in one call

curl "https://rate-api.com/api/v1/convert?from=KRW&to=USD&amount=100" \
  -H "X-API-Key: YOUR_KEY"

The response includes the rate, the result and a timestamp so you can cache responsibly.

Tips for 2026

Always store the timestamp alongside any converted amount, prefer the mid-market rate for display, and set up a rate alert if your business is sensitive to KRW volatility.
