What this estimate assumes
- Uses Korea Eximbank AP01 base and telegraphic-transfer rates.
- JPY is officially quoted per 100 yen and is normalized to one yen for calculations.
- Rates are checked after 11:00, 14:00 and 18:00 KST only when a visitor requests the calculator; weekends and holidays may show the latest business day.
- Long-term charts use the Bank of Korea ECOS 731Y001 daily base-rate series; the CNH selection uses ECOS CNY history as a clearly labeled reference.
- Cash-exchange fees, card fees and bank-specific preferential discounts are excluded.

AUD10,000 for tuition
At KRW900 per AUD, AUD10,000 converts to about KRW9 million at the base rate.
Common questions
Why can this differ from a search engine quote?
Providers, timestamps and rate types differ. Firessem uses the Korea Eximbank date and rate displayed on this page.
Will I receive exactly this amount?
No. Your bank or card issuer can apply cash spreads, transfer fees, card fees or preferential-rate discounts.
Does the rate update on weekends?
A new official rate may not be published on weekends or Korean public holidays, so the latest business-day rate is shown.
