About this tool
Convert ether to finney instantly. Free, bidirectional, and fully in-browser.
1 ether equals 1000 finney — enter any ether value to convert it to finney instantly. This Ether to Finney (milliether) converter is a client-side tool: it applies a single multiplication (finney = ETH × 1000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert finney back to ether. A reference table lists common ether values already converted, and nothing you enter is sent to a server.
Open Ether to Finney (milliether) Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Ether field.
Read the equivalent in finney in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert finney to ether.
The result updates as you type, and the swap button flips the conversion to finney (milliether) → ether without reloading.
The conversion uses the precise factor (finney = ETH × 1000), 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 ether is 1000 finney. Multiply the ether value by 1000 to convert. For example, 10 ETH = 10000 finney.
finney = ETH × 1000. This tool applies it automatically and shows a worked example: 10 ETH = 10000 finney.
Yes. Press the swap button, or type into the finney (milliether) field, and the tool converts finney to ether using the inverse of the same relationship.
It uses the standard Ethereum denomination definition (finney = ETH × 1000), 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.
