What is a terawatt (TW)?

A terawatt is an SI unit of power equal to 10^12 watts, representing extremely large rates of energy transfer or generation.

How is joule per second (J/s) related to watts?

One joule per second (J/s) is exactly equal to one watt, measuring the rate at which energy is transferred or expended.

Why convert terawatts to joules per second?

Converting terawatts to joules per second translates very large power units into the fundamental SI unit usable in detailed physics, engineering, and energy analyses.
