What is a sat?
A sat, short for satoshi, is the smallest unit of bitcoin: one hundred-millionth of a coin.
One bitcoin equals 100,000,000 sats. The name honors Satoshi Nakamoto, Bitcoin's pseudonymous creator.
You never have to buy a whole bitcoin. At a price of $76,000, $100 buys about 131,579 sats. Many bitcoiners quote small amounts in sats because whole numbers are easier to read than 0.00131579 BTC.
Quick conversions
- 1 BTC = 100,000,000 sats

Inside the Bitcoin software itself, every amount is counted in sats. Bitcoin is only shown as decimals to make it familiar.
