Currency Converter

The currency converter turns an amount in one currency into its equivalent in another using a reference rate table held by the site. You enter the amount, choose the currency you are converting from and the currency you want, and the tool returns the converted figure, the exact pair rate expressed as one unit of the source currency, and a short list of comparison values in other widely traded currencies. It is aimed at shoppers comparing overseas prices, freelancers quoting in a client's currency, travellers budgeting a trip, and anyone who needs a quick sense of scale rather than a dealing price. Rates are maintained in the site's settings rather than pulled live from a market feed, so treat the output as an indicative guide. For an actual transaction, check the rate your bank, card issuer or payment provider will apply.

Every currency in the table is stored as a rate against a single base currency, the US dollar. That one column of numbers is enough to convert any pair without storing a separate rate for each combination, which would need hundreds of entries.

A conversion runs in two steps. First the tool divides your amount by the rate of the currency you are converting from, which expresses the amount in the base currency. Then it multiplies that base figure by the rate of the target currency. Written as one expression, the result equals amount multiplied by the target rate divided by the source rate.

The pair rate shown underneath is the same ratio applied to a single unit: target rate divided by source rate. Because both steps use the stored table rather than a live feed, the same inputs always give the same answer until the stored rates are updated. Alongside the main result, the tool converts your amount into several commonly quoted currencies so you can sanity-check the scale of the figure at a glance.

Suppose the stored table holds the US dollar at 1, the euro at 0.92 and the pound sterling at 0.79. You want to convert 250 pounds into euros.

Step one converts the amount into the base currency: 250 divided by 0.79 gives 316.4557 US dollars. Step two multiplies that by the euro rate: 316.4557 multiplied by 0.92 gives 291.1392 euros.

The pair rate is 0.92 divided by 0.79, which equals 1.164557. Checking the result the other way round, 250 multiplied by 1.164557 also gives 291.14 euros, so the two routes agree.

The comparison list uses the same base figure of 316.4557 dollars. Multiplied by a yen rate of 148.5 it gives 46,993.66 yen, and multiplied by a Canadian dollar rate of 1.36 it gives 430.38 Canadian dollars. Reverse the direction and the arithmetic mirrors: 291.1392 euros divided by 0.92 and multiplied by 0.79 returns the original 250 pounds, give or take rounding in the final decimal place.

The converted amount tells you roughly what a price is worth in a currency you understand. That is exactly what you need when you are comparing a hotel rate, a supplier quote or an overseas purchase, and it is usually accurate enough that a decision does not hinge on the last few pennies.

What it does not tell you is what you will actually pay. Real transactions add a spread on top of the mid-market rate, plus card fees, ATM charges or transfer commissions, and the rate applied is the one in force at the moment the payment settles rather than when you looked it up. Currencies can also move by more than a percent in a day, so a figure checked last week may already be stale.

A further limit is specific to this tool: the rates come from a table held in the site's settings, not from a live market feed, so they are only as current as the last update. Use the result as a guide, verify anything financially significant against your bank or provider, and treat this as information rather than financial advice.
