What this converter does
This converter changes bitcoin amounts between BTC and satoshis. A satoshi is the smallest standard unit of bitcoin. One BTC equals exactly 100,000,000 satoshis.
Inputs and results
Conversion chooses the direction: BTC to satoshis or satoshis to BTC. Amount is the value you want to convert. Optional BTC price in USD lets you estimate the dollar value using a price you provide.
The converted amount shows the equivalent BTC or satoshi value. The USD estimate appears only when you enter a BTC price; no live market price is fetched.
How the conversion works
To convert BTC to satoshis, multiply BTC by 100,000,000. To convert satoshis to BTC, divide satoshis by 100,000,000. The optional USD estimate multiplies the BTC amount by the manual BTC price.
Worked example
0.001 BTC equals 100,000 satoshis. If you enter a BTC price of $100,000, then 0.001 BTC is estimated at $100. If you convert 250,000 satoshis to BTC, the result is 0.0025 BTC.
Tips for interpreting results
People often use satoshis for small bitcoin amounts because decimals like 0.000025 BTC are harder to read. USD estimates can change quickly because bitcoin prices move, so enter a current price if dollar value matters.
