mW to W

milliwatt

• Definition: A milliwatt is a unit of power equal to one thousandth of a watt. It is commonly used to measure small amounts of power in various devices.

• Symbol: The symbol for milliwatt is mW.

• Usage: Milliwatts are often used in electronics, telecommunications, and other fields where low power consumption is critical, such as in battery-operated devices.

watt

• Definition: A watt is a unit of power in the International System of Units (SI) that measures the rate of energy transfer. It is defined as one joule per second.

• Symbol: The symbol for watt is W.

• Usage: Watts are widely used to quantify electrical power, mechanical power, and thermal power, making it a fundamental unit in physics and engineering.

Origin of the milliwatt

• The term milliwatt is derived from the prefix “milli,” which means one thousandth, combined with the unit “watt.” The milliwatt was introduced to provide a convenient way to express small amounts of power without resorting to fractions of watts.

Origin of the watt

• The watt is named after James Watt, an 18th-century Scottish inventor and mechanical engineer who made significant improvements to the steam engine. The unit was adopted in the late 19th century to honor his contributions to the field of energy and power.
