About the Satoshi Calculator

One Bitcoin equals 100,000,000 satoshis. Thinking in sats is practical because a single coin is now expensive, while everyday amounts are easier to read as whole numbers of satoshis.

Lightning Network payments, tips and many wallets quote balances in sats, so a quick conversion helps you understand what a number really means in your own currency.

What Is a Satoshi?

A satoshi, often shortened to sat, is the smallest unit of Bitcoin. One Bitcoin equals 100,000,000 satoshis, so one satoshi is 0.00000001 BTC. The unit is named after Satoshi Nakamoto, the pseudonymous creator of Bitcoin.

Because a whole Bitcoin is expensive, many people now think in sats. Prices, tips and Lightning Network payments are commonly quoted in satoshis because the numbers are easier to read than long decimals.
