Convert kilowatt to attowatt
Please provide values below to convert kilowatt [kW] to attowatt [aW], or Convert attowatt to kilowatt.
1 kW = 1.0000e+21 aW. To convert kilowatt to attowatt, multiply the value by 1.0000e+21; to go the other way, divide by it (1 aW = 1.0000e-21 kW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kW = 1.0000e+21 aW
- 1 aW = 1.0000e-21 kW
- 10 kW = 1.0000e+22 aW
- 100 kW = 1.0000e+23 aW
How to Convert Kilowatt to Attowatt
1 kW = 1e+21 aW
Example: convert 15 kW to aW:
15 kW = 15 × 1e+21 aW = 1.5e+22 aW

Kilowatt
A kilowatt (kW) is a unit of power equal to 1,000 watts, used to measure the rate of energy transfer or consumption.
History/Origin
The kilowatt was introduced as part of the metric system to provide a practical unit for measuring larger power outputs, especially in engineering and electrical contexts, and has been widely adopted since the 20th century.
Current Use
The kilowatt is commonly used today to specify the power output of engines, electrical appliances, and power generation facilities, as well as in billing for electricity consumption and capacity ratings.
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.
