Currency converter

Type an amount, a currency and where to: 100 usd to gbp, £50 in eur, 20 dollars to yen, or usd to gbp for a rate.

How it works

Rates come from Frankfurter, which publishes central-bank reference rates for about 150 currencies, updated once per working day. Your browser fetches them the first time you type a currency conversion, then caches them for six hours, so later conversions are instant. If you are offline it uses the last cached rates and marks the result “(offline, cached)”.

Ways to type it

• Codes: 100 usd to gbp
• Symbols: £50 in eur ($ means US dollars: use cad or aud for the others)
• Names: 20 dollars to yen
• No amount: usd to gbp assumes 1
• A calculation as the amount: 2*50 eur to usd

These are reference rates, not trading rates: good for estimating, not for settling invoices.

Units win ties: 10 km to miles is a unit conversion, and 100 pounds to kg is weight while 100 pounds to usd is money.
