What does one attowatt represent?

One attowatt represents an extremely small power unit equal to 10^-18 watts, used to describe very low levels of energy transfer.

Why use calorie (th)/second instead of watts?

Calorie (th)/second reflects thermal power based on thermochemical calories, useful in calorimetry and older engineering literature.

Can this converter be used for everyday power measurements?

No, this converter is intended for very small power levels typical in scientific and experimental contexts rather than everyday applications.
