About this tool
Convert finney to mwei instantly. Free, bidirectional, and fully in-browser.
1 finney (milliether) equals 1000000000 mwei — enter any finney (milliether) value to convert it to mwei instantly. This Finney (milliether) to Mwei (lovelace) converter is a client-side tool: it applies a single multiplication (mwei = finney × 1000000000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert mwei back to finney. A reference table lists common finney (milliether) values already converted, and nothing you enter is sent to a server.
Open Finney (milliether) to Mwei (lovelace) Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Finney (milliether) field.

Use the decimal-places slider for more or less precision, or press swap to convert mwei to finney.
The result updates as you type, and the swap button flips the conversion to mwei (lovelace) → finney (milliether) without reloading.
The conversion uses the precise factor (mwei = finney × 1000000000), 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.
