Watt is the SI unit of power.

In the metric system, milli is the prefix for 10^{–}³.

Therefore, a milliwatt (mW) is equal to one thousandth of a watt.

**Formula to convert mW to W.**

Since we know that a mW is equal to one thousandth of a watt.

Therefore, to convert mW to W, we divide the milliwatt value by 1,000.

**Power in W = Power in mW** **÷ 1,000**

**Example:**

Convert 5,000 milliwatts to watts.

**= 5,000** **÷ 1,000** ** **

**= 5 watts**
