About this tool
Convert watts to megawatts instantly. Free, bidirectional, and fully in-browser.
1 watt equals 1e-6 megawatts — enter any watt value to convert it to megawatts instantly. This Watt to Megawatt converter is a client-side tool: it applies a single multiplication (MW = W × 1e-6) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert megawatts back to watts. A reference table lists common watt values already converted, and nothing you enter is sent to a server.
Open Watt to Megawatt Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Watt field.
Read the equivalent in megawatts in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert megawatts to watts.
The result updates as you type, and the swap button flips the conversion to megawatt → watt without reloading.
The conversion uses the precise factor (MW = W × 1e-6), 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 watt is 1e-6 megawatts. Multiply the watt value by 1e-6 to convert. For example, 10 W = 1e-5 MW.
MW = W × 1e-6. This tool applies it automatically and shows a worked example: 10 W = 1e-5 MW.
Yes. Press the swap button, or type into the megawatt field, and the tool converts megawatts to watts using the inverse of the same relationship.
It uses the standard power definition (MW = W × 1e-6), 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.
