What does one watt represent in terms of energy?

One watt equals one joule of energy transferred per second, representing the rate of energy usage or production.

Why convert watts to attojoule per second?

To quantify and analyze extremely small power levels found in advanced scientific and microelectronic applications.

Are conversions between watt and attojoule/second practical for everyday use?

No, attojoule/second units are mainly used for ultra-low power measurements requiring sensitive equipment, not general power calculations.
