How much is $100 in Bitcoin today?
This converter shows, in real time, how many satoshis you get when you trade dollars, euros or reais for Bitcoin. The satoshi is Bitcoin's smallest unit: 1 BTC equals 100,000,000 sats. When the price of 1 BTC is high, $100 buys few sats; when the price drops, the same $100 buys more. Thinking in sats helps you see the real purchasing power of your money in Bitcoin.
The calculation uses the current Bitcoin price (public source: CoinGecko) and applies an approximate spread to reflect a real purchase. Formula: sats = (amount ÷ BTC price) × (1 − spread) × 100,000,000. Everything runs in your browser, in real time, sending nothing to our servers.
