What is an attowatt (aW)?

An attowatt is an extremely small unit of power equal to 10^-18 watts, commonly used to measure very low-power phenomena in scientific and nanoscale devices.

How is kilojoule per second (kJ/s) related to watts?

Kilojoule per second is equivalent in magnitude to a kilowatt, meaning 1 kJ/s equals 1,000 watts.

Why convert attowatts to kilojoule per second?

Users convert between these units to express tiny power measurements in a more conventional unit useful for engineering and industrial analysis.
