Bitcoin and Satoshis: BTC to Satoshi Conversion Explained
A satoshi (often called a "sat") is the smallest unit of bitcoin recorded on the network: one hundred-millionth of a bitcoin. Converting between the two is a fixed multiplication — no exchange rate involved.

What a satoshi is
Bitcoin amounts are tracked on-chain in whole satoshis, named after Bitcoin's pseudonymous creator, Satoshi Nakamoto. One BTC is divisible into 100 million of them, so a satoshi is 0.00000001 BTC.
Formula
Satoshis = BTC × 100,000,000 BTC = Satoshis ÷ 100,000,000
Examples
| BTC | Satoshis |
|---|---|
| 1 | 100,000,000 |
| 0.1 | 10,000,000 |
| 0.0025 | 250,000 |
| 0.0005 | 50,000 |
| 0.00000001 | 1 |
Worked example
Converting 50,000 sats to BTC
- 50,000 ÷ 100,000,000
= 0.0005 BTC
Why small amounts are written in sats
Amounts like 0.00034 BTC are easy to misread — one misplaced zero changes the value tenfold. Writing 34,000 sats is clearer. Wallets and payment apps often let you switch display units for this reason, and network fees are commonly quoted in sats per virtual byte.
Converting to dollars
To turn sats into dollars, first convert to BTC, then multiply by a BTC price you supply. MoneyTools doesn't fetch live prices; use the Crypto Converter with a rate you enter.
How to use the converter
- Open the BTC to Satoshi Converter.
