What is a satoshi?
Bitcoin’s smallest unit
A satoshi is the smallest unit of Bitcoin, named after Satoshi Nakamoto. One Bitcoin equals exactly 100,000,000 satoshis. Abbreviation: sat / sats.
Why denominate in sats?
As Bitcoin’s dollar price rises, whole-BTC decimals get unwieldy. “25,000 sats” is clearer than “0.00025 BTC,” and you do not need a whole coin to own bitcoin.
The conversion math
sats = round(usd × 100,000,000 ÷ BTC-USD). Right now that unit rate is 1,292 sats per $1 at $77,378.24 BTC-USD.
