Convert watt to attowatt

Enter a value below to convert watt [W] to attowatt [aW]. Reverse conversion: Convert attowatt to watt.

1 W = 1.0000e+18 aW. To convert watt to attowatt, multiply the value by 1.0000e+18; to go the other way, divide by it (1 aW = 1.0000e-18 W). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Watt: Definition and Use

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.


Attowatt: Definition and Use

An attowatt (aW) is a unit of power equal to 10^-18 watts, representing an extremely small amount of power.

History/Origin

The attowatt is part of the SI prefix system introduced to denote very small quantities, with 'atto-' representing 10^-18. It has been used mainly in scientific contexts to measure minuscule power levels.

Current Use

The attowatt is rarely used in practical applications but may be referenced in scientific research involving extremely low power measurements, such as in quantum physics or nanotechnology.
