How currency conversion works

Use a live catalogue and a published mid-market reference rate.

1Catalogue then rate

OmniCalc loads currency codes, names and symbols from the provider. It then requests a rate for the selected pair. If a pair is missing, the app reports that instead of inventing a number. Convert with amount × rate.

2Reference rates

Frankfurter blended rates are mid-market reference values, not live bid/ask quotes and not money-transfer prices. Banks and apps add spread, fees and delays.
