One satoshi (or ‘sat’) is the smallest unit in Bitcoin: 100,000,000 sats = 1 BTC. Much day-to-day Bitcoin activity - Lightning payments, fee estimates, small trades - is expressed in sats rather than whole bitcoins, for convenience. With the calculator below, you can switch between the two (and into fiat currency, like dollars or pounds) instantly.

How it works
One bitcoin equals 100,000,000 sats. That’s one hundred millionth of a bitcoin. The unit was named to honour Satoshi Nakamoto, the pseudonymous creator of the world’s first decentralized cryptocurrency.
| Satoshis | BTC Equivalent |
|---|---|
| 1 | 0.00000001 BTC |
| 10 | 0.00000010 BTC |
| 100 | 0.00000100 BTC |
| 1,000 | 0.00001000 BTC |
| 10,000 | 0.00010000 BTC |
| 100,000 | 0.00100000 BTC |
| 1,000,000 | 0.01000000 BTC |
| 10,000,000 | 0.10000000 BTC |
| 100,000,000 | 1.00000000 BTC |
In the calculator above, the three inputs mirror each other, meaning it can do the conversion in any direction you need. Whether you’re sanity checking how many sats to send as a tip or checking the fiat equivalent of a fee quoted in satoshis per vByte, you’ll get an answer instantly as you type.
No reloads, no fiddly dropdowns, and no other crypto coins. That’s all this one aims to do. Enjoy - and mind the zeros.
