Convert watts to attowatt
Watt
The watt (symbol: W ) is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 joule per second, and is used to quantify the rate of energy transfer. In SI base units, the watt is described as kg⋅m 2 ⋅s −3 , which can be demonstrated to be coherent by dimensional analysis. The watt is named after James Watt, an 18th-century Scottish inventor.
Attowatt
The attowatt (aW) is a unit of power equal to 10−18 watts. Power levels at this scale are encountered in fundamental quantum experiments, single-molecule spectroscopy, and the detection of gravitational waves, where extraordinarily sensitive instrumentation is required. The attowatt represents a frontier measurement scale where quantum noise and thermal fluctuations become dominant engineering considerations.
