Convert milliwatt to watt
Please provide values below to convert milliwatt [mW] to watt [W], or Convert watt to milliwatt.
1 mW = 0.001 W. To convert milliwatt to watt, multiply the value by 0.001; to go the other way, divide by it (1 W = 1000 mW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mW = 0.001 W
- 1 W = 1000 mW
- 10 mW = 0.01 W
- 100 mW = 0.1 W
How to Convert Milliwatt to Watt
1 mW = 0.001 W
Example: convert 15 mW to W:
15 mW = 15 × 0.001 W = 0.015 W

Milliwatt
A milliwatt (mW) is a unit of power equal to one thousandth of a watt, used to measure small amounts of power.
History/Origin
The milliwatt was introduced as part of the metric system to provide a convenient unit for measuring low power levels, especially in electronics and telecommunications, with its usage expanding alongside the adoption of the watt as the standard power unit.
Current Use
Milliwatts are commonly used today in electronics, audio equipment, and wireless communication devices to specify power levels, such as in battery-powered devices, LED brightness, and signal transmission power.
Watt
The watt (W) is the SI unit of power, defined as one joule per second, representing the rate of energy transfer or conversion.
History/Origin
The watt was named after James Watt, the Scottish engineer and inventor, in 1889. It was adopted as the SI unit of power to standardize measurements in science and engineering.
Current Use
The watt is widely used today to quantify power in electrical devices, engines, and energy consumption, serving as a fundamental unit in physics, engineering, and everyday applications.
Frequently Asked Questions
What is 1 milliwatt in watt?
1 milliwatt (mW) = 0.001 watt (W).
How do you convert milliwatt to watt?
Multiply the milliwatt value by 0.001. For example, 25 mW × 0.001 = 0.025 W.
What is 10 milliwatt in watt?
10 mW = 0.01 W.
Which unit is larger, the milliwatt or the watt?
The watt is the larger unit: 1 mW equals only 0.001 W.
