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