Unit Explanations
AttowattaW
Source UnitAn attowatt (aW) is a unit of power in the International System of Units (SI), representing one quintillionth (10^-18) of a watt. It is used to measure extremely low levels of power, often in scientific fields such as quantum mechanics and photonics. The attowatt is particularly useful in contexts where minute power levels need to be quantified, such as in the study of nanotechnology, bioengineering, and certain physics applications. The use of this unit allows researchers to work with precise measurements that are critical in advanced scientific experiments and applications.
Current Use
Attowatts are currently utilized in various advanced scientific fields, including quantum computing, nanotechnology, and biomedical engineering. For instance, in quantum computing, measuring the power consumption of qubits can involve attowatts as researchers aim to minimize energy use. Furthermore, attowatts play a crucial role in photonics, particularly in the measurement of light power emitted from lasers and LEDs at micro and nano scales. Countries leading in these technologies include the USA, Germany, and Japan, where cutting-edge research is prevalent.
Fun Fact
An attowatt is so small that it would take a billion of them to equal just one microwatt.
WattW
Target 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.

The use of this unit allows researchers to work with precise measurements that are critical in advanced scientific experiments and applications.
History & Origin
The term 'attowatt' was introduced in the 1970s as part of a systematic approach to naming units in the metric system. It is derived from the SI prefix 'atto-', which denotes a factor of 10^-18, combined with the base unit 'watt', named after the Scottish inventor James Watt. The adoption of the attowatt as a recognized unit reflects the increasing need for precise measurements in fields that operate at extremely small scales, particularly in modern physics and technology.
Etymology: The prefix 'atto-' comes from the Danish word 'atten', meaning 'eighteen'. The watt, named after James Watt, is a measure of power.
