About Milliwatts (mW) to Watts (W) Conversion

What are Milliwatts and Watts?

Milliwatts (mW) and watts (W) 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.
• Watt (W): The standard unit of power in the International System of Units (SI). It's defined as one joule per second and is used to quantify the rate of energy transfer.

Formula for Milliwatts to Watts Conversion

The formula to convert milliwatts to watts is:

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

Where:

• \(W\) is the power in watts
• \(mW\) is the power in milliwatts

Calculation Steps

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

Example

Let's convert 5,000 milliwatts to watts:

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

Visual representation:

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