Frequently asked questions

How much is 1 Bitcoin (BTC) in USD?
The value of 1 BTC in US dollars changes every second with the market. The converter above shows the current Bitcoin-to-USD rate live — averaged across major exchanges — and updates in real time as prices move.
How is the BTC to USD price calculated?
btcusd.io fetches the BTC/USD price from several major exchanges in parallel (including Coinbase, Kraken, Bitstamp, Gemini and CoinGecko) and averages them, so you get a fair mid-market rate rather than a single venue's quote.
Can I convert USD back into BTC?
Yes. The converter is bidirectional — type a USD amount and it instantly shows how much Bitcoin that buys at the current rate, or type a BTC amount to see its dollar value.
Does the BTC price update in real time?
Yes. Prices stream live over a WebSocket connection and fall back to polling every few seconds, so the Bitcoin to USD rate you see is always current.
