关于货币换算器
Convert an amount between about 160 currencies at the latest daily reference rates. Rates come from the ExchangeRate-API open-access feed, with the European Central Bank's reference rates (via Frankfurter) as the fallback; the page shows which source and date it used.
The conversion itself is computed in 50-digit decimal from the two currencies' rates against the US dollar, and the result is rounded to the target currency's minor unit (two decimals for most, none for the yen). A quick-reference table lists common amounts in both directions, and a chart shows the last 90 days for currency pairs the ECB publishes.
These are mid-market rates. Banks and card networks add a margin, so the amount you are charged will usually be lower than shown.

常见问题
How often are the exchange rates updated?
The rate feed updates once a day, and the page shows the time of the last update. The app keeps the most recent rates on your device and fetches new ones when the saved copy is more than 12 hours old, so conversions keep working offline with the last known rates.
Why is my bank's rate different?
The rates here are mid-market reference rates, halfway between buying and selling prices. Banks, card networks and exchange bureaus add a margin to that rate and some add a fixed fee, so the rate on your statement will differ.
Which currencies have a history chart?
The 90-day chart uses the European Central Bank's reference rates, published for about 30 currencies including USD, EUR, GBP, INR, JPY, CNY, AUD and CAD. Pairs involving other currencies, such as AED or SAR, show a note instead of a chart.
“货币换算器”有多准确？
准确性取决于输入值和方法的假设。十进制运算使用50位有效数字，但估算、数值方法和源数据的精度可能较低；显示时的舍入并不能消除这些限制。 已按独立来源核验的计算示例：3。 例如，“100 at 83.5”根据100 × 83.5; 1/83.5进行核验。
