About this tool
Convert gwei to mwei instantly. Free, bidirectional, and fully in-browser.
1 gwei (shannon) equals 1000 mwei — enter any gwei (shannon) value to convert it to mwei instantly. This Gwei (shannon) to Mwei (lovelace) converter is a client-side tool: it applies a single multiplication (mwei = gwei × 1000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert mwei 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 Mwei (lovelace) 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 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 gwei.
The result updates as you type, and the swap button flips the conversion to mwei (lovelace) → gwei (shannon) without reloading.
The conversion uses the precise factor (mwei = gwei × 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 gwei (shannon) is 1000 mwei. Multiply the gwei (shannon) value by 1000 to convert. For example, 10 gwei = 10000 mwei.
