Use the switch button between the fields to reverse the conversion direction.

The exact conversion path available at checkout can also affect the final amount.\n          <\/p>\n        <\/details>\n\n        <details class=\"gcp-faq-item\">\n          <summary>Is this page useful if I only know my budget?<\/summary>\n          <p>\n            Yes.

This is a simple way to compare conversion outcomes faster.\n          <\/p>\n        <\/details>\n\n        <details class=\"gcp-faq-item\">\n          <summary>Does the calculator update with market conditions?<\/summary>\n          <p>\n            The estimate is based on currently available market data used by the widget, so values can change as market conditions change. That is why the page is best for fast conversion checks rather than fixed quotes.\n          <\/p>\n        <\/details>\n\n        <details class=\"gcp-faq-item\">\n          <summary>When is an <span data-bind=\"coin-name\">Optimism<\/span> calculator most helpful?<\/summary>\n          <p>\n            It is most helpful when you need a quick answer before buying, budgeting, comparing fiat currencies, or checking the value of a specific <span data-bind=\"coin\">OP<\/span> amount.
