Convert an amount between major currencies using a built-in reference rate table, or your own exchange rate. Quick estimates for travel and shopping across borders.
Pick the currency you're converting from and to, enter an amount, and (optionally) override the exchange rate with today's live rate. The built-in table gives indicative rates only.

A currency calculator converts money between currencies using an exchange rate. The built-in reference table is indicative only — for a real transaction, enter today's live rate in the 'Custom rate' field.
Converted = amount × rate, where rate = how many units of the target currency one unit of the source buys. Rates are derived from a USD reference table: rate = to(USD) / from(USD).
No. The built-in table is a static snapshot for estimation only and goes stale quickly. Always enter a current rate from your bank or a forex provider before relying on a figure.
Card networks and banks apply their own exchange rate plus possible foreign-transaction fees (often 1–3%). The mid-market rate you see online is rarely what you actually pay.
