SATS is an abbreviation for Satoshis, which is the smallest unit of Bitcoin. Each Bitcoin can be divided into 100,000,000 satoshis. 1 Satoshi (SATS) equals 0.00000001 BTC. In the Bitcoin blockchain and its source code, all Bitcoin quantities are priced in satoshis. These amounts are converted to Bitcoin for familiarity and readability.
