kWh to MWh Calculator | Convert Kilowatt Hours to Megawatt Hours
Understanding how to convert kWh to MWh is essential when dealing with electricity consumption, energy production, or large-scale power management. Both kilowatt-hours (kWh) and megawatt-hours (MWh) are standard units of energy, but they differ by a factor of one thousand. Whether you’re analyzing household energy usage, estimating solar output, or comparing industrial power generation, knowing how to perform a kWh to MWh conversion helps you make accurate and informed energy calculations.
In this guide, we’ll explain what kWh and MWh mean, show you how to convert kWh to MWh using a simple formula, and provide a kWh to MWh calculator for quick reference.
What Is kWh and MWh?
Both kilowatt-hours (kWh) and megawatt-hours (MWh) are units of energy commonly used to measure electricity generation and consumption. The main difference between the two lies in scale:
1 Megawatt-hour (MWh) = 1,000 Kilowatt-hours (kWh)
A kilowatt-hour (kWh) represents the amount of energy used when a 1,000-watt appliance operates for one hour. For example, if a 2,000-watt air conditioner runs for half an hour, it consumes 1 kWh of electricity. It’s the standard unit you’ll see on household electricity bills.
A megawatt-hour (MWh), on the other hand, is a larger measurement typically used for industrial or utility-scale applications. Power plants, data centers, and renewable energy projects often measure their energy production or storage capacity in MWh. For instance, a solar farm that generates 5,000 kWh of energy per day produces 5 MWh daily.
Understanding these two units is the foundation of accurate kWh to MWh conversion, helping individuals and businesses track and manage their energy more efficiently.
How to Convert kWh to MWh
Converting kilowatt-hours (kWh) to megawatt-hours (MWh) is a simple process once you understand the relationship between the two units. Since 1 MWh = 1,000 kWh, you just need to divide the number of kilowatt-hours by 1,000.
Here’s the kWh to MWh conversion formula:
MWh=kWh÷1000
Where:
kWh = kilowatt-hours (the amount of energy used)
MWh = megawatt-hours (a larger unit of energy)
This formula helps you easily convert kWh to MWh in any situation.
Example:
If a solar farm produces 5,000 kWh of electricity in one day, you can convert it to MWh by dividing by 1,000:
MWh=5000÷1000 =5 MWh
So, 5,000 kWh equals 5 MWh.
This simple kWh to MWh conversion formula is useful for understanding energy reports, electricity bills, and renewable energy data in larger-scale measurements.
kWh to MWh Conversion Table
To make energy conversion even easier, you can use the following kWh to MWh conversion table as a quick reference. Since 1 MWh = 1,000 kWh, each value in kilowatt-hours can be divided by 1,000 to find its equivalent in megawatt-hours.
Kilowatt-hours (kWh) | Megawatt-hours (MWh) |
1 kWh | 0.001 MWh |
10 kWh | 0.01 MWh |
50 kWh | 0.05 MWh |
100 kWh | 0.1 MWh |
500 kWh | 0.5 MWh |
1,000 kWh | 1 MWh |
5,000 kWh | 5 MWh |
10,000 kWh | 10 MWh |
50,000 kWh | 50 MWh |
100,000 kWh | 100 MWh |
You can also use an online kWh to MWh calculator to instantly perform these conversions without manual calculation. This is especially useful for engineers, homeowners with solar systems, or anyone tracking electricity production and usage.
Real-World Examples of kWh to MWh Conversion
Understanding kWh to MWh conversion is easier when applied to real-world energy use. For example:
Household Energy Storage: A standard home may consume 30 kWh per day, which is 0.03 MWh. This daily consumption includes energy for lighting, cooking, heating, and running various appliances. To store this energy for backup during power outages or to use it in off-grid situations, a portable power station is a highly effective solution.
For example, the EcoFlow DELTA 3 Plus Portable Power Station, with an expandable capacity ranging from 1 kWh to 5 kWh, can power essential household appliances like refrigerators, lights, and chargers for several hours. When a household’s daily consumption (0.03 MWh) is considered, a single DELTA 3 Plus unit, paired with the Smart Extra Battery, can efficiently handle temporary power outages, ensuring comfort and energy availability without the need for a full home backup system.

FAQs
Is 1000 kWh a MWh?
Yes, 1,000 kilowatt-hours (kWh) is equal to 1 megawatt-hour (MWh). This is because the “mega” prefix represents one million watts, and a megawatt-hour measures energy at a scale 1,000 times larger than a kilowatt-hour. To convert kWh to MWh, simply divide the kWh value by 1,000. For example, 1,000 kWh ÷ 1,000 = 1 MWh. This conversion is commonly used in energy production, utility billing, and renewable energy planning, helping households, businesses, and power plants understand electricity consumption in larger, more manageable units.
How many kWh is 1 MWh?
1 megawatt-hour (MWh) equals 1,000 kilowatt-hours (kWh). Since 1 kWh represents the energy used by a 1,000-watt appliance operating for one hour, a megawatt-hour scales this up by 1,000 times. For instance, if a solar farm generates 1 MWh in an hour, that’s equivalent to 1,000 kWh of energy produced. This conversion is essential for understanding large-scale energy usage, such as industrial facilities, commercial buildings, or renewable energy systems. It ensures consistency when comparing smaller household usage to utility or power plant outputs.
How do I calculate MWh?
To calculate megawatt-hours (MWh), divide the total kilowatt-hours (kWh) by 1,000. The formula is simple: MWh = kWh ÷ 1,000. For example, if a factory consumes 5,000 kWh, its energy usage in MWh would be 5,000 ÷ 1,000 = 5 MWh. This calculation helps convert household, commercial, or industrial energy consumption into a larger unit, making it easier to interpret bills, estimate solar energy production, or plan battery storage. Using MWh also simplifies energy reporting for utility companies and renewable energy projects.
