    Why the satoshi exists

    Bitcoin records amounts as integers of the smallest unit, named after Satoshi Nakamoto. Every on-chain balance is really a whole number of satoshis, which avoids rounding errors that would come from storing fractional values. Fee rates use the same unit: a rate of 12 sat/vB means twelve satoshis for each virtual byte of transaction data.

    Frequently Asked Questions

    How many satoshis are in one Bitcoin?

    Exactly 100,000,000 satoshis make one bitcoin. The satoshi is the smallest unit Bitcoin can record on-chain, so 1 sat is 0.00000001 BTC.

    Why do faucets and apps pay in satoshis?

    Small rewards are easier to read as whole numbers. A payout of 500 sats is clearer than 0.000005 BTC, so most micro-earning platforms display satoshis instead of BTC.

    Does this converter need a price?

    No. BTC and satoshis are two units of the same asset, so the conversion is a fixed ratio and needs no market data. Nothing you type is sent anywhere — the calculation runs entirely in your browser.
