환율 계산기

What this tool does

Choose an amount and two currencies to get the converted amount at the latest rates. It converts among 13 currencies: Korean won, US dollar, Japanese yen, euro, Chinese yuan, British pound, Australian dollar, Canadian dollar, Swiss franc, Hong Kong dollar, Singapore dollar, Thai baht and Vietnamese dong, and shows the unit rate below, such as '1 USD = ○○○○.○○○○ KRW'. Use it to plan a travel budget or estimate overseas shop prices and card charges in your home currency.

How it is calculated

When the page opens, it fetches each currency's rate against one US dollar from a public exchange rate service. Conversion between any two other currencies is a cross rate through the dollar: amount × (target rate ÷ source rate). For instance, if at that moment 1 dollar were 1,380 won and 145 yen, 10,000 yen would be 10,000 × 1,380 ÷ 145 ≈ 95,172 won (assumed rates for illustration). Won, yen and dong results are rounded to whole numbers with thousands separators; other currencies show two decimals. Editing the amount or switching currencies recalculates instantly, and the ⇅ button in the middle swaps the source and target. If the rates cannot be loaded, a message asks you to try again later.

• Pick the source currency at the top and type an amount. It starts at 1 US dollar.
• Pick the target currency below. It starts as Korean won.
• The converted amount appears right away, with the unit rate to four decimals underneath.
• Press ⇅ to reverse the direction, for example won to dollars.
• Reload the page to fetch fresh rates.

Things to know

• The figures are close to the mid-market rate. Real bank exchanges and card payments add a buy-sell spread and fees, so you will get less than shown.
• The rate provider generally updates about once a day, so on volatile days the figure can differ from live market prices. No update time is shown on screen.
• Many Korean banks quote yen per 100 yen. This calculator works per 1 yen, so enter 100 when comparing.
• Conversions into dong or won are rounded to whole numbers. Multiply by the unit rate yourself if you need decimals.
• When paying abroad, choosing to pay in your home currency (DCC) often adds the merchant's rate and extra fees, so paying in local currency is usually the default to prefer.
• Before exchanging a large sum, look at the trend over several days and compare banks' preferential rates.
