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