Sats ⇄ BTC ⇄ USD at the live market price. One Bitcoin = 100,000,000 satoshis.
Type into any field above and the other two update instantly using the live Bitcoin price. One Bitcoin always equals 100,000,000 satoshis; what changes is how many dollars that stack of sats commands. The converter refreshes the price every minute so quick mental math — 'how much is 50k sats?' — always uses current market data.
Satoshi (sat) is the base unit of the Bitcoin network: 0.00000001 BTC. Everything on-chain is accounted in sats — the decimal 'bitcoin' is just a human-friendly display convention, like quoting money in thousands.
At any price you can anchor three numbers: sats per dollar (Moscow Time), the value of 1,000 sats (a common Lightning tip), and the value of 1 sat. The widget keeps all three pinned above, live. When Bitcoin crosses $100,000, the round numbers get satisfying: $1 = 1,000 sats exactly.
Pricing in sats reframes accumulation: instead of owning 0.015 BTC you own 1.5 million sats. Same value, better ergonomics — and increasingly the convention in Lightning apps, tipping and merchant tools.
