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