Convert milliwatts to watts

Convert milliwatts to watts by entering a value below.

1 mW (milliwatts) = 1000000 W (watts)

How to Convert Milliwatts to Watts

The milliwatt and watt are both units of power. By definition, 1 milliwatt equals exactly 1000000 watts. This means to convert milliwatts to watts, you multiply by 1000000.

Formula

watts = milliwatts × 1000000

Step-by-Step Example

Convert 5 mW to watts:

1
Convert 5 mW to watts

We need to convert milliwatts to watts

2
Apply the formula

Since 1 mW = 1000000 W, multiply by 1000000

5 × 1000000 = 5000000

Answer

5 mW = 5000000 W

About These Units

Milliwatt (mW)

A milliwatt (mW) equals 0.001 watts or one-thousandth of a watt. Milliwatts measure laser pointer power (1-5 mW), wireless signal strength (WiFi: 30-100 mW), LED indicator lights, and low-power electronics. Bluetooth devices typically transmit at 1-100 mW.

Watt (W)

The watt (W) is the SI unit of power equal to one joule per second. Watts measure electrical power consumption (LED bulb: 10W, microwave: 1000W), light bulb brightness, and device power ratings. One kilowatt equals 1,000 watts. Named after inventor James Watt.
