Convert between satoshis and whole Bitcoin using the fixed factor of one hundred million satoshis per BTC. A satoshi is the smallest unit of Bitcoin, named after its pseudonymous creator, and it is the unit that on chain amounts, mempool fees and Lightning payments are actually denominated in. Because Bitcoin has exactly eight decimal places, this converter keeps full precision so a value like 250000 satoshis maps cleanly to 0.0025 BTC with no rounding drift. Type into either field and the other updates instantly. This is useful for reading raw transaction outputs, sizing a Lightning invoice, or checking how many sats a fee really costs. All calculations happen locally in your browser, so nothing you enter is sent to a server and the exact satoshi count is always preserved.
