What is a satoshi?
A satoshi, or sat, is the smallest unit of bitcoin the blockchain records: 1 sat = 0.00000001 BTC, and 100,000,000 sats = 1 BTC. It's named after Satoshi Nakamoto, Bitcoin's pseudonymous creator. "Satoshi to USD" and "sats to USD" are the same conversion. To get dollars, multiply the number of sats by the bitcoin price and divide by 100 million.
Wallets and apps increasingly show balances in sats because "25,000 sats" is easier to read than "0.00025 BTC". On the Lightning Network, a payment layer on top of Bitcoin, amounts are tracked even more finely, in thousandths of a sat (millisatoshis), though anything settled on the main blockchain is rounded to whole sats.
Fees are counted in sats too
Bitcoin network fees are quoted in sats per virtual byte (sat/vB). A simple payment is about 140 vbytes, so at 10 sat/vB it costs about 1,400 sats, which is … at today's price. The fee depends on the transaction's size and how busy the network is, not the amount sent. Try your own numbers in the network fee calculator.
"Dust": amounts too small to send
Bitcoin Core, the most widely used node software, by default won't relay a transaction that creates an output smaller than a "dust" threshold, which is 546 sats for older address types (it's lower for newer ones). Even above that, a small amount can cost more in fees to spend later than it's worth. That's why the 546 row is in the table, and why tiny amounts are better sent over Lightning.
What changes the value of a sat
A sat is always exactly one hundred-millionth of a bitcoin, so its dollar value moves with the bitcoin price and nothing else. See what moves the bitcoin price.
How to check a price safely
- Go to the source yourself. Type the address of your exchange or a big price tracker, or use a bookmark. Search ads and links in messages can lead to copycat sites.
- A price is never a reason to rush. "The price is about to jump, buy now" is the oldest pressure tactic there is.
- Fake trading sites show fake numbers. Scam "platforms" display made-up prices and balances that seem to grow, then demand a "tax" or "unlock fee" before you can withdraw. If you can't withdraw, the balance isn't real. Read how to spot fake crypto trading sites.
- Checking a price never needs your wallet. No converter, this one included, should ask you to connect a wallet, sign anything or type a seed phrase. Anything that does is a scam.
