Currency Converter

The currency converter converts between 15 major world currencies using live mid-market rates sourced from the European Central Bank (ECB) via the Frankfurter API. Rates are updated daily. Enter an amount, choose a from and to currency, and get the converted result instantly — along with the reverse rate and a grid of popular conversions for quick reference. This tool is useful for travel planning, understanding international prices, back-of-envelope financial calculations, and quick reference when comparing cross-border costs. It displays the mid-market rate — the fairest benchmark — and is designed for estimation and reference, not for live trading or foreign exchange transactions. For exact rates before making a bank transfer, booking international travel, or conducting business transactions, always verify with your bank or payment provider. Banks and exchange services apply a spread above the mid-market rate shown here.

The Maths Behind Currency Converter

Converted Amount = (Input Amount ÷ From Rate) × To Rate | All rates relative to USD = 1.0

Formula: Result = (Amount ÷ From Rate) × To Rate All rates are stored relative to USD as the base currency (USD = 1.0). To convert between any two currencies, first convert the amount to USD by dividing by the from-currency rate, then multiply by the to-currency rate. Example: Convert £500 GBP to EUR. GBP rate = 0.79 (meaning £0.79 = $1 USD) EUR rate = 0.92 USD equivalent = £500 ÷ 0.79 = $632.91 EUR result = $632.91 × 0.92 = €582.28 Reverse rate (1 EUR in GBP) = GBP rate ÷ EUR rate = 0.79 ÷ 0.92 = 0.858. The 15 currencies included are USD, GBP, EUR, AUD, CAD, INR, JPY, CHF, NZD, SGD, HKD, MXN, BRL, ZAR, and SEK — covering the most commonly exchanged pairs globally.
