货币转换器
使用透明且带日期的汇率快照在主要世界货币之间转换。
关于这个计算器
使用透明的汇率快照在美元、欧元、英镑、日元、人民币等主要货币之间转换。本工具会显示汇率的采集日期，并在数据过期时提醒你，让你清楚是否可以信任结果。汇率为静态快照，并非实时市场数据。
How to use the currency converter
- Enter the amount you want to convert.
- Choose the currency you are converting from and the one you are converting to.
- Read the converted amount and the exchange rate used.
- Check the snapshot date — if a stale warning appears, treat the result as an estimate.
常见示例
- 100 美元 → 欧元，快照汇率 0.92 → €92.00

- 1 美元 → 人民币，快照汇率 7.24 → ¥7.24
常见问题
Are these exchange rates live?
No. The converter ships with a static, dated snapshot of representative rates so it works reliably offline and without a paid data feed. The page always shows the snapshot date and warns when the rates are stale. A live data source is a planned future addition.
Why does it warn that the rates are out of date?
The snapshot has a fixed capture date. When that date is older than the freshness threshold, the converter shows a warning so you treat the result as an approximation rather than a real-time quote.
How is a cross rate between two non-USD currencies calculated?
Every rate is stored relative to a common base (USD). To convert from one currency to another, the tool divides the destination rate by the source rate, so the base cancels out and the math stays exact.
Can I share a specific conversion?
Yes. The amount and both currencies live in the URL, so copying the address bar reopens the exact same conversion for anyone who clicks the link.
