Currency conversion guide for travellers

A currency converter tells you what something costs in money you understand. Here is what the numbers mean, why the rate you're offered differs from the one you see here, and some simple habits that keep fees down when you travel.

What the rate here is

This converter shows a mid-market reference rate, the midpoint between what big banks pay to buy and to sell a currency, published once a day. It's the fairest yardstick for comparing offers, but it's not a price anyone will necessarily sell you money at. Banks, card networks, exchange booths and airport kiosks add a margin to the rate, a fee, or both.

How the math works

Rates are quoted against one base currency. To go from currency A to B, the converter divides B's rate by A's rate and multiplies by the amount. If 1 EUR = 1.10 USD and 1 EUR = 20.0 MXN (example figures only), then 1 USD = 20.0 ÷ 1.10 = 18.18 MXN, so a 500 MXN dinner is 500 ÷ 18.18 = 27.50 USD.

Quick mental math

Find a round number close to the current rate and use it in your head. If a peso rate is close to 20 per dollar, dividing a peso price by 20 (halve it, then drop a zero) gives a quick dollar estimate: 350 MXN → about 17.50 USD. Check the exact figure in the converter for bigger purchases.

Checking the real cost of an offer

Compare what you would get with the mid-market amount. If the converter says 100 USD = 1,818 MXN and a booth offers 1,700 MXN, you are paying about 118 MXN, or 6.5%, compared with the reference rate. That's the number to compare across options, including any flat fee.

Practical tips

Pay in the local currency. When a card terminal or ATM offers to charge you in your home currency (often called dynamic currency conversion), the conversion is done at a rate the merchant's provider chooses. Choosing the local currency usually lets your card network convert instead. Check your card's own foreign transaction fee too.
Know your bank's ATM and foreign fees before you go, and take out fewer, larger amounts if your bank charges per withdrawal.
Airport exchange counters are convenient but are often among the most expensive options. Compare their quote with the converter.
Save the rates before you fly. Open the converter once while you're online. It keeps the last rates on your device for use offline.

Budgeting a trip

Before a trip, convert a few everyday prices you expect to see, like a coffee, a taxi ride, a meal, and a night's lodging, so you can recognise a fair price at a glance. Then decide how you'll pay for each: card where it's widely accepted, cash for markets, small shops and tips. If your card charges a foreign transaction fee, add that percentage to the converted price to see what you'll really pay. A 3% fee on a 2,000-peso hotel bill is 60 pesos. When you return, leftover coins usually can't be exchanged, so spend them or keep them for your next visit.

Common mistakes

Mistake	Fix
Converting the wrong way (multiplying instead of dividing)	Use the ⇅ swap and read the big number
Assuming the screen rate is what you'll get	Expect a margin; compare offers against it
Accepting conversion at the terminal	Pay in local currency where possible
Using a stale rate	Check "Last updated" on the converter

How it works

Type an amount on the keypad and the converted amount appears below it. Tap a currency to change it, tap ⇅ to swap. Rates are daily mid-market reference rates quoted against the euro, so A to B is rate(B) ÷ rate(A) × amount. The latest rates are saved on your device, so the converter keeps working offline and shows when they were last updated.

Rates come from the free fawazahmed0 currency-api (CC0), with Frankfurter (European Central Bank reference rates) as a backup. Flags are standard emoji, drawn by your device's own emoji font. For information only, not for trading. Banks, cards and exchange booths add fees and spreads.

FAQ

Does it work offline?

Yes. Open it once with a connection and the rates are saved on your device. Offline it uses those saved rates and shows when they were last updated.

How often are rates updated?

Once a day. Each time you open the converter online it fetches the newest daily rates.

Why is my bank's rate different?

These are mid-market reference rates. Banks, card networks and exchange booths add a margin or fee on top.

Where are travel mode and tip?

Tap ☰ More, then Travel & tip. Set your home and trip currencies, see a quick price-check table, and add a tip to the amount on the main screen.

What is the mid-market rate?

It's the midpoint between the buy and sell rates large banks trade at. It's a fair reference, but retail providers add a margin or fee on top.

Should I pay in my home currency or the local currency abroad?

Usually the local currency. If the terminal converts to your home currency, its provider sets the rate, which often includes a margin.
