Unit Explanations
WattW
Source UnitThe watt (symbol: W) is the SI unit of power, defined as the rate of energy transfer equivalent to one joule per second. It measures the amount of energy conversion or transfer that occurs per unit time. In practical terms, it quantifies the rate at which work is done or energy is consumed. The watt is a derived unit in the International System of Units (SI), and it is used extensively in various fields such as electricity, mechanics, and thermodynamics to quantify power output or consumption.
Current Use
The watt is widely used across the globe to measure electrical power, mechanical power, and heat transfer. It serves as a fundamental unit in the fields of electrical engineering, physics, and many applied sciences. It is crucial for calculating energy consumption in households, industries, and for determining the power output of engines and machinery.
Fun Fact
One watt is equivalent to 1/746th of a horsepower.
MilliwattmW
Target UnitThe milliwatt (mW) is a unit of power in the International System of Units (SI), defined as one-thousandth of a watt (0.001 W). It is a measure of the rate of energy transfer or conversion over time, where one watt is equivalent to one joule per second. The milliwatt is commonly used to express small amounts of power, particularly in fields like electronics, telecommunications, and medical devices, where precise measurements are crucial. It enables engineers and scientists to quantify energy consumption and efficiency in low-power applications.
Current Use
Today, the milliwatt is widely used in various industries, including telecommunications, computing, and healthcare, to measure power consumptions of devices ranging from smartphones to medical implants. It is particularly valuable in assessing the efficiency and energy usage of low-power electronics, which are increasingly prevalent in modern technology.
Fun Fact
The milliwatt is commonly used in measuring the power output of fiber optic transmitters.

Milliwatt
power • Non-SI
Definition
The milliwatt (mW) is a unit of power in the International System of Units (SI), defined as one-thousandth of a watt (0.001 W). It is a measure of the rate of energy transfer or conversion over time, where one watt is equivalent to one joule per second. The milliwatt is commonly used to express small amounts of power, particularly in fields like electronics, telecommunications, and medical devices, where precise measurements are crucial. It enables engineers and scientists to quantify energy consumption and efficiency in low-power applications.
History & Origin
The concept of power measurement dates back to the late 18th century when James Watt developed the steam engine. To quantify the power of steam engines, the watt was later defined in his honor. The milliwatt emerged as a convenient sub-unit to express smaller power values, particularly useful in the burgeoning fields of electrical engineering and telecommunications during the 20th century.
Etymology: The term 'milli' is derived from the Latin word 'mille,' meaning 'thousand.' Therefore, 'milliwatt' literally translates to 'one-thousandth of a watt.'
Current Use
Today, the milliwatt is widely used in various industries, including telecommunications, computing, and healthcare, to measure power consumptions of devices ranging from smartphones to medical implants. It is particularly valuable in assessing the efficiency and energy usage of low-power electronics, which are increasingly prevalent in modern technology.
💡 Fun Facts
