The conversion from MWh to kWh, and from kWh to MWh is easy mathematics. However, you must understand each formula to convert these units accurately. These unit conversions are crucial when handling or installing solar energy and other electrical applications.

If you are intentional about saving your money on energy bills, you must learn about various features of electricity, including megawatt-hours and kilowatt-hours, and how they influence your electricity consumption.

Moreover, if you plan to mount solar panels, understanding kilowatts and megawatts is fundamental, as this will help you select the right solar system and manage your solar energy efficiently.

The basic conversion formula from kWh to MWh is 1 kWh ÷ 1000 = 0.001 MWh, therefore, 1 kWh = 0.001 MWh while the formula for converting from megawatts to kilowatts is equals MWh = 1000 kWh.

This article will give you comprehensive knowledge about Kilowatt-Hours and Megawatt-Hours, and how to convert from one unit to another. So, keep reading.

What is Kilowatt-Hours?

What is Kilowatts Hour

The unit symbol for Kilowatt-hours is commonly abbreviated as kWh. kWh should not be mistaken for kW, as these are different units used for measuring different things.

The Kilowatt-hours (kWh) indicates the amount of electricity consumed within a specified period. It is the measure of energy. How do you measure the energy? You will multiply the consumed kilowatts with the time when power is required, i.e.

Energy=Power x Time

Therefore, if a coffee maker consumes 1kW of power and is operating for five hours, it will utilize 5kWh of energy. If a 1,000-watt light bulb consumes 1,000 watts/hour, the 1,000 watts is converted into 1 kWh.

The power used by a household appliance or machine is measured in Watts, while the energy used is measured in kWh. If a 1000-watt machine has been working for three hours, the electricity spent by the machine is 3 kWh (1kWh x 3 hours 3kWh). Higher wattage and longer hours translate to more electricity consumption.

What Is a Kilowatt-Hour Capable of Powering?

Here are some of the practical applications one kilowatt-hour is capable of powering:

  • It can power an average home for approximately 50 minutes
  • It can keep a modern refrigerator running for about 20 hours
  • It can light up two 60-watt bulbs for at least 8.3 hours
  • It is capable of toasting 89 bread slices
  • It is capable of driving an electric car for over 3.6 miles
  • It can run a home swimming pool for about 2.8 hours
  • It can melt approximately 2.2 ounces of aluminum

As you can observe from the above, one kilowatt-hour goes a long way. Energy-efficient appliances and electronics operate on low-wattage. Therefore, the fewer the kilowatt hours, the lower the electricity bills.

What is Megawatt-Hours?

Megawatt-hour (MWh) is a measurement unit for quantifying the amount of energy generated over a defined period. Note, that a megawatt (MW) and a megawatt-hour (MWh) do not mean the same thing.

A single MWh is equivalent to the amount of energy generated in one hour. Also, Megawatt-hours estimate the amount of energy required to power vehicles, machines, or household appliances within a specified period.

What Can You Do with a Megawatt-Hour Power?

One megawatt-hour is a considerable amount of power. For instance, a megawatt-hour of power can keep two 60-watt bulbs and two modern refrigerators powered uninterrupted for one year.

A single megawatt-hour can power an electric vehicle for over 3,600 miles, which is comparable to driving from Los Angeles to New York City and still having a considerable amount of power left on the battery.

Another demonstration of what a megawatt-hour can do is running a regular American household for 1.2 months. Other things it is capable of powering include:

  • Toasting approximately 90,000 bread slices
  • Operate a swimming pool pump continuously for over five months
  • Melt about 137 pounds of aluminum
  • Power two modern refrigerators for one year

Convert Kilowatt-Hours to Megawatt-Hours: A Step-by-Step Guide

One megawatt equals 1,000kW. Similarly, one megawatt-hour is equal to 1,000kWh.

How do you convert kilowatt-hours to megawatt-hours (kWh to MWh)? Divide the energy with this conversion ratio: 1,000 kilowatt-hours ÷ megawatt-hour.

The formula for converting to megawatt-hours = kilowatt-hours ÷ 1,000. Thus, a megawatt-hours = kilowatt-hours ÷ 1,000.

The amount of energy in megawatt-hours is equivalent to the amount of energy in kilowatt-hours, then divided by 1,000.

Example: Convert 500 kilowatt-hours to megawatt-hours.

Method: Megawatt-hours = 500 kWh ÷ 1,000= 0.5 MWh.

In simple terms, the conversion formula is:

  • 1 kWh = 0.001 MWh
  • 1 MWh = 1000 kWh 

Example: How do you convert 15 kWh to MWh?

15 kWh= 15 x 0.001 MWh= 0.015 MWh.
