📐 How We Calculate This

Unit conversions use exact mathematical ratios defined by the International Bureau of Weights and Measures (BIPM). Currency conversions reference mid-market exchange rates updated daily from the European Central Bank and Federal Reserve.

Currency rates fluctuate throughout the day. The rates shown are indicative — actual exchange rates at your bank or transfer service will differ due to spreads and fees.
