About this tool
Convert kwei to mwei instantly. Free, bidirectional, and fully in-browser.
1 kwei (babbage) equals 0.001 mwei — enter any kwei (babbage) value to convert it to mwei instantly. This Kwei (babbage) to Mwei (lovelace) converter is a client-side tool: it applies a single multiplication (mwei = kwei × 0.001) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert mwei back to kwei. A reference table lists common kwei (babbage) values already converted, and nothing you enter is sent to a server.
Open Kwei (babbage) to Mwei (lovelace) Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Kwei (babbage) field.
Read the equivalent in mwei in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert mwei to kwei.
The result updates as you type, and the swap button flips the conversion to mwei (lovelace) → kwei (babbage) without reloading.
The conversion uses the precise factor (mwei = kwei × 0.001), 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 kwei (babbage) is 0.001 mwei. Multiply the kwei (babbage) value by 0.001 to convert. For example, 10 kwei = 0.01 mwei.
mwei = kwei × 0.001. This tool applies it automatically and shows a worked example: 10 kwei = 0.01 mwei.
Yes. Press the swap button, or type into the mwei (lovelace) field, and the tool converts mwei to kwei using the inverse of the same relationship.
It uses the standard Ethereum denomination definition (mwei = kwei × 0.001), 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.
