Convert Megawatt-hour to Kilowatt-hour

Quick answer: Megawatt-hour to Kilowatt-hour

1 Megawatt-hour = 1,000Kilowatt-hour (MWh → kWh). To convert megawatt-hour to kilowatt-hour, multiply by 1,000. To convert kilowatt-hour to megawatt-hour, multiply by 0.001. The converter at the top does this instantly and both ways; the sections below give the formula, worked examples, a full conversion chart and answers to the most common megawatt-hour-to-kilowatt-hour questions.

How to convert Megawatt-hour to Kilowatt-hour

To convert megawatt-hour to kilowatt-hour, multiply the number of megawatt-hour by the conversion factor 1,000, because 1 MWh = 1,000kWh. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 kWh = 0.001MWh, so you divide by 1,000 (or multiply by 0.001) to turn kilowatt-hour back into megawatt-hour.

kWh = MWh × 1,000  ·  MWh = kWh × 0.001

1. Write down the value you want to convert, in megawatt-hour.
2. Multiply it by 1,000.
3. The result is the same area/length/quantity expressed in kilowatt-hour.

Megawatt-hour to Kilowatt-hour conversion chart (both directions)

The chart below converts megawatt-hour to kilowatt-hour and kilowatt-hour to megawatt-hour side by side, so it works whichever way you need. 1 megawatt-hour = 1,000kilowatt-hour, and 1 kilowatt-hour = 0.001megawatt-hour.

Megawatt-hour vs Kilowatt-hour: which is bigger?

A megawatt-hour is the larger unit: one megawatt-hour equals 1,000 kilowatt-hours. Put another way, you need 1,000 kilowatt-hours to make a single megawatt-hour.

What is a Megawatt-hour? History, origin and usage

The megawatt-hour is one million watt-hours (1,000 kilowatt-hours), the natural scale for the output of power stations and large industrial loads. Like its smaller relatives it derives from the watt, named after James Watt.

Megawatt-hours measure generation and consumption at grid scale — the daily output of a power plant, the energy traded on wholesale electricity markets, and the capacity of grid-scale batteries. Larger still are the gigawatt-hour (GWh) and terawatt-hour (TWh) used for national-scale figures.

A 1-megawatt generator running flat out for one hour produces one megawatt-hour — roughly the daily electricity use of dozens of average homes. Wholesale electricity is typically priced per megawatt-hour rather than per kilowatt-hour.

What is a Kilowatt-hour? History, origin and usage

The kilowatt-hour — 1,000 watt-hours — became the universal trading unit of electrical energy as power grids spread in the late 19th and early 20th centuries. It rests on the watt, named after James Watt, scaled up to the household level.

The kilowatt-hour is the “unit” your electricity meter records and your utility bills you for; appliance running costs are worked out by multiplying an item’s kilowatt rating by the hours it runs and the price per kWh. It is the single most important energy unit in domestic and commercial energy.

One kilowatt-hour equals exactly 3.6 megajoules (3,600,000 joules), because a kilowatt is 1,000 joules per second and an hour is 3,600 seconds. Running a 1,000-watt appliance for one hour consumes exactly one kilowatt-hour — the figure people informally call a “unit” of electricity.

Tips for converting Megawatt-hour to Kilowatt-hour

• To go from megawatt-hour to kilowatt-hour, multiply by 1,000; to go back, divide by 1,000 (or multiply by 0.001).
• For a quick mental estimate, remember that 1 megawatt-hour ≈ 1,000 kilowatt-hour, so 10 megawatt-hour ≈ 10,000 kilowatt-hour.
• The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
• Both fields update live as you type — change either side to convert in that direction.

How to use this Megawatt-hour to Kilowatt-hour converter

Type a number into the Megawatt-hour field and the equivalent in Kilowatt-hour appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Kilowatt-hour field to convert the other way (kilowatt-hour to megawatt-hour). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.

Accuracy and method

Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 MWh = 1,000kWh), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for megawatt-hour-to-kilowatt-hour conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.

How do I convert megawatt-hour to kilowatt-hour?

Multiply the number of megawatt-hour by 1,000. For example, 10 megawatt-hour = 10 × 1,000 = 10,000 kilowatt-hour, and 25 megawatt-hour = 25,000 kilowatt-hour.

How many megawatt-hour are in 1 kilowatt-hour?

1 kilowatt-hour = 0.001 megawatt-hour. So to convert kilowatt-hour back to megawatt-hour, multiply by 0.001.

What is the formula to convert megawatt-hour to kilowatt-hour?

kilowatt-hour = megawatt-hour × 1,000. The reverse formula is megawatt-hour = kilowatt-hour × 0.001.

How much is 100 megawatt-hour in kilowatt-hour?

100 megawatt-hour = 100,000 kilowatt-hour. (And 1000 megawatt-hour = 1,000,000 kilowatt-hour.)

Which is bigger, a megawatt-hour or a kilowatt-hour?

A megawatt-hour is larger: 1 megawatt-hour = 1,000 kilowatt-hour.

Is this megawatt-hour to kilowatt-hour converter accurate?

Yes — every value is computed from the exact 1,000 kWh per MWh factor (not rounded look-up tables), and the factors are re-verified automatically on every update.

Can I convert kilowatt-hour to megawatt-hour too?

Yes. The converter works both ways — enter a value in either field. 1 kilowatt-hour = 0.001 megawatt-hour.
