About this tool
Convert bitcoin to satoshi instantly. Free, bidirectional, and fully in-browser.
1 bitcoin equals 100000000 satoshi — enter any bitcoin value to convert it to satoshi instantly. This Bitcoin to Satoshi converter is a client-side tool: it applies a single multiplication (sat = BTC × 100000000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert satoshi back to bitcoin. A reference table lists common bitcoin values already converted, and nothing you enter is sent to a server.
Open Bitcoin to Satoshi Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Bitcoin field.
Read the equivalent in satoshi in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert satoshi to bitcoin.
The result updates as you type, and the swap button flips the conversion to satoshi → bitcoin without reloading.
The conversion uses the precise factor (sat = BTC × 100000000), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One bitcoin is 100000000 satoshi. Multiply the bitcoin value by 100000000 to convert. For example, 10 BTC = 1000000000 sat.
sat = BTC × 100000000. This tool applies it automatically and shows a worked example: 10 BTC = 1000000000 sat.
Yes. Press the swap button, or type into the satoshi field, and the tool converts satoshi to bitcoin using the inverse of the same relationship.
It uses the standard Bitcoin denomination definition (sat = BTC × 100000000), not a rounded approximation, so results are exact to the number of decimal places you select.
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
