About RateWick

RateWick is a reference tool for two everyday questions: how much is one currency in another, and how do two units relate. Both answers come from published, authoritative sources — not from forecasts or opinions.

Where the data comes from

Exchange rates are derived from the European Central Bank euro foreign-exchange reference rates, published once per business day around 16:00 CET since 1999. Cross rates between non-euro currencies are computed from the published EUR-based table. These are reference rates for information — banks and card issuers add their own margin to any transaction.

Unit conversions use exact standard definitions (SI factors, international yard and pound agreements, and the affine definitions of temperature scales).

What you will find on every currency page

The latest reference rate and its date, the inverse rate, the 52-week high and low with dates, one-year change, annualised volatility, ten-year yearly averages, a 12-month chart, the last 30 published days, and a converter.

Honest limits

• Reference rates are daily, not real-time — there is one fix per business day and none on weekends or TARGET holidays.
• Currencies that left the reference series keep their pages as history; the last published date is stated on every such page.
• No warranty: verify critical figures with your bank or broker before transacting.
