How to convert multiple currencies at once

Start with one base currency

Your base currency is the currency of the amount you enter. If you enter 100 EUR, every result should represent the equivalent of those same 100 euros. Selecting USD as the base changes what your input means; 100 USD is a different starting value.

Choose your home currency when comparing a familiar budget abroad. Choose the seller’s currency when checking a listed price in currencies used by different people. The right base depends on the question you want to answer.

Use the multi-currency view

1. Open Worldwide Currency Converter and switch to its multi-currency view.
2. Select the currency of your starting amount.
3. Enter the amount you want to compare.
4. Choose the currencies you want to see together.
5. Read each result as an equivalent of the original amount.

You can also try the multi-currency section on our website. For repeated use on Android, the app keeps the converter accessible alongside its offline conversion feature.

A worked example

Suppose the example rates are 1 EUR = 1.10 USD, 1 EUR = 0.85 GBP, and 1 EUR = 100 INR. A base amount of 100 EUR would produce the following results:

These are three ways to express the same starting value. Adding 110, 85, and 10,000 together would mix different units and would not give you a meaningful total.

Compare prices that start in different currencies

A different task is comparing a price of 80 EUR with another price of 90 USD. Convert both prices to one common currency first. At the example rate above, 80 EUR becomes 88 USD, which can then be compared with 90 USD.

Before deciding that an item costs less, compare what is included. Shipping, taxes, quantities, and payment-provider fees may change the final total. The converter supplies the currency arithmetic, not those additional costs.

Avoid three common mistakes

• Changing the base unintentionally. Check the code beside your input every time you switch currencies.
• Reading an equivalent as an extra amount. Each output is a conversion of the same input.
• Mixing rates from different times. Refresh before a comparison when you need current estimates. Offline results use cached rates.

When checking the calculation yourself, keep the full rate until the final rounding step. Our exchange-rate formula guide explains multiplication, division, and reversing a quote.

When is this useful?

Multi-currency view is useful when planning a route through several countries, discussing a budget with people who use different currencies, or getting a quick reference for an international price. A single pair is often enough for a one-off calculation; multiple results help when the question has several destinations.
