How the USD to BTC conversion works
Enter an amount in US Dollar and the converter shows the value in Bitcoin at the live mid-market rate. The rate line below it gives both directions, and the at-a-glance list shows the same amount in other popular currencies and coins.
In the smart calculator you can mix currencies with arithmetic: 100 USD to BTC or $20 + €15 in BTC.

Questions and answers
How is the USD to BTC rate calculated?
ConvertEasy fetches live rates for every currency against the US dollar, then divides: USD→BTC = (USD in USD) ÷ (BTC in USD). The primary source is Coinbase's public exchange-rate feed, with CoinGecko for crypto prices and currency-api and the European Central Bank (via Frankfurter) as fallbacks.
How often do the rates update?
Every minute while the page is open, and whenever you come back to the tab. The status line under the converter shows the source and how long ago the rates were fetched.
Why is my bank's USD to BTC rate different?
These are mid-market reference rates. Banks, card networks, remittance services and exchanges add a spread and sometimes a fee, so the rate you are offered is usually a little worse.
Is the Bitcoin price live?
Yes. Crypto trades around the clock, so the price is taken from Coinbase, with CoinGecko as a fallback, and refreshed every minute. Prices on individual exchanges can differ slightly.
Does the currency converter work offline?
Yes. The last rates fetched are stored in your browser, so conversions keep working with no connection. The converter labels them as an offline copy with the time they were fetched.
