What is an attowatt used to measure?

An attowatt is used to express extremely small power levels such as those in ultra-sensitive detectors, nanoelectronics, and cryogenic physics experiments.

Where are terawatts commonly applied?

Terawatts quantify very large power amounts, including national electricity generation, large power plants' capacity, and enormous astrophysical power outputs.

Why is converting between attowatts and terawatts uncommon in practice?

Because the scale difference is enormous, conversions between attowatts and terawatts are mostly theoretical or for illustrative purposes and are rarely practical.
