About this calculator
A satoshi is the smallest unit of bitcoin, named after its pseudonymous creator Satoshi Nakamoto. One bitcoin is divisible into exactly 100,000,000 satoshis, so a satoshi is 0.00000001 BTC. As bitcoin's price has risen, people increasingly think and transact in satoshis ("sats") for small amounts — the way you might use cents instead of dollars. This converter moves between the two units using the fixed 100-million ratio, and also expresses the amount in "bits" (microbitcoin, equal to 100 satoshis). If you enter a current bitcoin price in US dollars, it will additionally value your amount in USD. The conversion between sats and BTC is exact and never changes; only the dollar value moves with the market, and this tool uses the price you supply rather than a live feed.
How it works — the formula
1 BTC = 100,000,000 sats
BTC = sats ÷ 100,000,000
USD = BTC × price per BTCThe unit conversion is a fixed power of ten; the dollar value layers on a user-supplied market price.
Worked examples
- Inputs:
- amount=50000, unit=sats, price=60000
- Output:
- 0.0005 BTC ≈ $30
- Inputs:
- amount=0.25, unit=btc, price=0
- Output:
- 25,000,000 sats
- Inputs:
- amount=1000000, unit=sats, price=50000
- Output:
- 0.01 BTC = $500
Limitations
- USD value uses the price you enter, not a live feed.
- Does not include exchange fees or spreads.
- Rounds BTC to 8 decimals (one satoshi).
Unit conversion is exact; dollar values are only as current as the price you supply.
