Currency Conversion

Same number, different units — convert and compare.

$100 in your pocket. Today's rate is 1 USD = 0.92 EUR. How many euros do you get?

Try this
100
euros = dollars × 0.92 (example rate, 1 USD = 0.92 EUR) = $100 → €92.00 (and €92.00 ÷ 0.92 = $100.00 back)

Multiply going one way, divide coming back

If 1 USD = 0.92 EUR, then dollars → euros means multiply by 0.92, and euros → dollars means divide by 0.92. The rate is just the exchange 'price' of one dollar, quoted in euros.

Your turn

At 1 USD = 0.92 EUR, how many euros do you get for $250 (ignoring fees)?

The 'mid-market' rate you see online isn't what you receive — banks, airport kiosks and apps take a cut, often 1–5%, by giving you a slightly worse rate or adding a flat fee.

Try it

Convert

100 × 0.92 = €92. Reverse: €92 ÷ 0.92 = $100.

Banks and apps charge a fee on top of the rate. The displayed rate is rarely what you actually get.
