Disclaimer: Our currency calculator uses Open Exchange API to gather current exchange rates. We pull new rates every 5 minutes to ensure that the conversion you see is accurate and up to date.

Cost-effective: Using an exchange rate API can be more cost-effective than developing and maintaining your own currency conversion system. Many API providers offer affordable pricing plans.
