attowatt to joule/second, or enter any two units below:

The SI prefix "atto" represents a factor of
10^{-18}, or in exponential notation, 1E-18.

So 1 attowatt = 10^{-18} watts.

The definition of a watt is as follows:

The watt (symbol: W) is the SI derived unit for power. It is equivalent to one joule per second (1 J/s), or in electrical units, one volt ampere (1 V·A).
