About this tool
Convert gwei to wei instantly. Free, bidirectional, and fully in-browser.
1 gwei (shannon) equals 1000000000 wei — enter any gwei (shannon) value to convert it to wei instantly. This Gwei (shannon) to Wei converter is a client-side tool: it applies a single multiplication (wei = gwei × 1000000000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert wei back to gwei. A reference table lists common gwei (shannon) values already converted, and nothing you enter is sent to a server.
Open Gwei (shannon) to Wei Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Gwei (shannon) field.
Read the equivalent in wei in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert wei to gwei.
The result updates as you type, and the swap button flips the conversion to wei → gwei (shannon) without reloading.
The conversion uses the precise factor (wei = gwei × 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.
