Formula & How It Works
Currency Conversion Formula
convertedAmount = amount × exchangeRateThe tool fetches the latest exchange rates for the "From" currency against all other currencies from the Frankfurter API (sourced from European Central Bank reference rates), then multiplies your entered amount by the rate for the selected "To" currency.
Inverse Rate
inverseRate = 1 ÷ exchangeRateThis shows how much of the "From" currency one unit of the "To" currency is worth, i.e. the reverse conversion rate.
Practical Examples & Common Use Cases
Converting US Dollars to Euros
If the USD to EUR rate is 0.9200, converting 100 USD gives 100 × 0.9200 = 92.00 EUR.
Converting British Pounds to Japanese Yen
If the GBP to JPY rate is 190.50, converting 50 GBP gives 50 × 190.50 = 9,525.00 JPY.
Finding the inverse rate
If 1 USD = 0.9200 EUR, the inverse rate is 1 ÷ 0.9200 ≈ 1.0870, meaning 1 EUR ≈ 1.0870 USD.
Frequently Asked Questions
The exchange rates are sourced from the European Central Bank (ECB) via the Frankfurter API. The ECB publishes updated reference rates every working day around 16:00 CET. Rates remain unchanged over weekends and European public holidays. These reference rates are widely used by financial institutions and businesses as a benchmark for currency conversions.
The rates displayed here are mid-market reference rates published by the European Central Bank. Banks and money transfer services typically add a markup (spread) on top of the mid-market rate to cover their costs and earn a profit. The difference can range from 0.5% to 5% or more depending on the institution, the currency pair, and the transaction amount. Always compare the total cost including fees and markup when choosing a service for actual money transfers.
Exchange rates are influenced by many factors including interest rate differentials between countries, inflation rates, trade balances, political stability, economic performance, and market speculation. Central bank monetary policies have a particularly strong impact. For example, when a central bank raises interest rates, its currency typically strengthens because higher rates attract foreign investment. Supply and demand in the global foreign exchange market, which trades over $7 trillion daily, ultimately determines the rate at any given moment.
These rates are reference rates intended for informational purposes such as budgeting, estimation, and general comparison. They should not be used as the definitive rate for actual financial transactions. For real money transfers, always check the rate offered by your bank, broker, or money transfer service at the time of the transaction, as rates change continuously and providers apply their own spreads and fees.
