About Milliwatts (mW) to Kilowatts (kW) Conversion

What are Milliwatts and Kilowatts?

Milliwatts (mW) and kilowatts (kW) are both units used to measure power, particularly in electrical and mechanical systems:

• Milliwatt (mW): A unit of power equal to one-thousandth of a watt. It's often used for measuring very small amounts of power.
• Kilowatt (kW): A unit of power equal to one thousand watts. It's commonly used for measuring larger amounts of power, such as in household electricity consumption or motor power ratings.

Formula for Milliwatts to Kilowatts Conversion

The formula to convert milliwatts to kilowatts is:

\[kW = \frac{mW}{1,000,000}\]

Where:

• \(kW\) is the power in kilowatts
• \(mW\) is the power in milliwatts

Calculation Steps

1. Identify the power in milliwatts.
2. Divide this value by 1,000,000 (since there are 1,000,000 milliwatts in a kilowatt).
3. The result is the equivalent power in kilowatts.

Example

Let's convert 5,000,000 milliwatts to kilowatts:

1. Given: \(mW = 5,000,000\)
2. Apply the formula: \(kW = \frac{5,000,000}{1,000,000}\)
3. Calculate: \(kW = 5\)

Visual representation:

Therefore, 5,000,000 milliwatts is equivalent to 5 kilowatts.
