What is a megawatt (MW)?

A megawatt is a unit of power equal to one million watts, used to quantify large power outputs such as those from power plants.

What does a milliwatt (mW) measure?

A milliwatt equals one thousandth of a watt and is used to express very low power levels in electronics and communications.

Why convert from MW to mW?

Converting MW to mW allows expressing very large power values in very small units, helping compare power across vastly different scales.

Key Features

Converts power units from megawatts to milliwatts with a precise conversion factor.
Supports understanding power scales across different domains like power plants and electronics.
Browser-based and easy to use for professionals and students in engineering and telecommunications.

Examples

Convert 2 MW: 2 × 1,000,000,000 mW = 2,000,000,000 mW
Convert 0.5 MW: 0.5 × 1,000,000,000 mW = 500,000,000 mW

Common Use Cases

Determining the power output of large generators and power plants.
Expressing low power levels of small electronic devices in milliwatts for detailed analysis.
Calculating and comparing power across utility-scale and microelectronic contexts.

Tips & Best Practices

Always verify unit selections carefully to avoid errors due to the large scale difference.
Use the converter to bridge measurements between high-capacity and low-power devices effectively.
Keep in mind that milliwatts are impractical for directly describing large utility-scale power outputs.

Limitations

The conversion involves a billion-fold scale difference, requiring careful handling to prevent mistakes.
Milliwatts are not suitable units for representing power on the scale of utility plants directly.
