Where does the exchange rate come from?

The rate box is pre-filled with the latest mid-market reference rate from our rate table, which is checked every hour against a public feed of daily reference rates. The line under the box shows when the rate was last updated and its source. Banks and card providers add a spread, so type your bank's rate over it when you need the exact amount.

How accurate is the conversion?

The math is exact to the precision your browser supports. The display rounds to 2 decimal places for both USD and MXN, matching standard currency formatting conventions.

Can I convert MXN back to USD?

Yes. Click the swap arrows button between the two fields to instantly reverse the conversion direction. The calculator automatically divides by your entered USD/MXN rate instead of multiplying.

Is my data sent to any server?

No. All calculation happens locally in your browser using JavaScript. Nothing you type is transmitted anywhere.

What exchange rate should I use?

Use the mid-market rate for a reference figure, or your bank's buy/sell rate for actual transactions. The USD/MXN rate fluctuates continuously, so always fetch a fresh rate before large transfers.

What is the Mexican Peso symbol?

The official symbol for the Mexican Peso is $ (same as USD). To avoid confusion, MXN is often written as "MX$". The ISO 4217 currency code is MXN.

What is the formula used for conversion?

USD to MXN: MXN amount = USD amount × rate. MXN to USD: USD amount = MXN amount ÷ rate. Both formulas are displayed on screen as you type.
