1 BTC = 100,000,000 satoshis. Currency value = BTC × rate per 1 BTC. Changing currency preserves the bitcoin amount.

Amounts are stored as whole satoshis. Input is rounded to the nearest satoshi, with halves rounded up; negative amounts are limited to zero and the upper bound to 21,000,000 BTC. The adjusted value appears when you leave the field. This is the tool’s bound based on MoneyRange in Bitcoin Core 29.0, not a claim about the exact amount issued.

Currency conversion is indicative: the rate may be cached and excludes spreads, fees and actual trade execution prices. Results use the currency’s decimal places; rounded display does not replace precise settlement accounting. Use the button to reload the rate. The time means receipt of the response, not the price measurement time.

100,000 satoshis = 0.001 BTC. At a hypothetical rate of 100,000 USD per BTC, the value is 100 USD. This example is not a current quote.
