Manual Currency Converter
Convert currency using a rate you supply.
Convert with your own rate
Live rates need a server; this deliberately uses a rate you enter, so it works offline and stays private. Type an amount and today's rate and it converts instantly — 100 at 1.08 is 108.
Because you supply the rate, it works on a plane or abroad with no connection, and you can enter the mid-market rate to see how much margin a card or exchange booth is really charging.
Rates move
Enter the mid-market rate you see, and remember banks add a margin. The amounts you enter never leave your browser.
