Milliwatts
A milliwatt (mW) is a unit of power equal to one thousandth of a watt. It is often used in contexts where power levels are low, such as in electronics and communications.
Watts
The watt (W) is the SI unit of power, defined as one joule per second. It is used to measure the rate of energy transfer and is commonly used in a wide range of applications, including electricity, mechanics, and heating.
