Introduction
Doing this by hand is slow and easy to get wrong – a dedicated online tool makes it a matter of seconds. Convert an amount between any two currencies using daily reference rates.
The result updates as you type, and a table shows the same amount in other major currencies.
In this guide you will learn what the Currency Converter does, how to use it step by step and how to avoid the most common mistakes. You can follow along with the free Currency Converter on WebToolsHelper – it runs in your browser and needs no sign-up.
What Is the Currency Converter and How Does It Work?
Convert between more than 160 world currencies using daily reference exchange rates. See the rate, the inverse rate and the amount in other major currencies.
Understanding exchange rates
An exchange rate is the price of one currency expressed in another. Most major currencies float: their rates move continuously as banks, businesses and investors trade, responding to interest rates, inflation, trade flows and expectations.
Some currencies are pegged, with a central bank holding the rate at or near a fixed value against the dollar or euro.
There is no single “the” rate. The wholesale market has a buying and a selling price, and retail customers are quoted rates with a margin on top.
A reference rate, such as the one a central bank publishes each working day, is a snapshot intended for comparison and bookkeeping. When you exchange money, compare the total you will receive after all fees rather than the headline rate alone.
For travel, the cheapest way to pay abroad is often a card that charges no foreign transaction fee, paying in the local currency. When a card terminal or cash machine offers to charge you in your home currency instead, a service called dynamic currency conversion, the rate it applies usually includes a markup of several per cent.
Declining that offer and choosing the local currency lets your card provider do the conversion, which is typically much closer to the mid-market rate.
How to Use the Currency Converter: Step-by-Step Guide
Open the Currency Converter and follow these steps:
- Step 1: Enter the amount you want to convert.
- Step 2: Choose the currency you have and the currency you want.

That is all – no installation, no account and no watermark.

Frequently Asked Questions About the Currency Converter
Where do the exchange rates come from?
From a published reference-rate feed that aggregates central bank and market data. The source and the date of the rates are shown beneath the result.
If that source is unavailable, European Central Bank reference rates are used instead.
How often are rates updated?
The source publishes rates once a day and this site refreshes its copy every few hours. They are indicative reference rates, not live trading prices.
Will I get this rate from my bank or card?
Usually not exactly. Banks, card issuers and money-transfer services add a margin and sometimes a fee, so the rate you receive is typically one to four percent worse than the mid-market reference rate.
What is the mid-market rate?
It is the midpoint between the prices at which currency is bought and sold on the wholesale market. It is the fairest single figure for comparison and is what converters like this one display.
Can I use these rates for accounting or trading?
They are suitable for estimates. For accounting, tax or trading, use the official rate required by your authority or the actual rate applied to your transaction.
