Convert attowatt to watt
Please provide values below to convert attowatt [aW] to watt [W], or Convert watt to attowatt.
1 aW = 1.0000e-18 W. To convert attowatt to watt, multiply the value by 1.0000e-18; to go the other way, divide by it (1 W = 1.0000e+18 aW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 aW = 1.0000e-18 W
- 1 W = 1.0000e+18 aW
- 10 aW = 1.0000e-17 W
- 100 aW = 1.0000e-16 W
How to Convert Attowatt to Watt
1 aW = 1e-18 W
Example: convert 15 aW to W:
15 aW = 15 × 1e-18 W = 1.5e-17 W

Attowatt
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.
Watt
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.
Frequently Asked Questions
What is 1 attowatt in watt?
1 attowatt (aW) = 1.0000e-18 watt (W).
How do you convert attowatt to watt?
Multiply the attowatt value by 1.0000e-18. For example, 25 aW × 1.0000e-18 = 2.5000e-17 W.
What is 10 attowatt in watt?
10 aW = 1.0000e-17 W.
Which unit is larger, the attowatt or the watt?
