Calculation & editorial methodology

How ApexConverter approaches formulas, units, accuracy, and corrections.

Calculation standards

We use documented formulas, standard conversion factors, and transparent display rounding. Inputs are validated in the browser. We do not silently replace invalid values with zero.

Currency rates

The Currency Converter requests indicative reference rates from the public open.er-api.com endpoint. Rates are not a transaction quote and may omit spreads, fees, taxes, and provider-specific pricing.

Corrections

Report a possible issue through our contact page. Material corrections are reviewed and dated.
