Question 63 of 72 What units would be best suited for 87 ,500,000,000 W? square

The question asks about the best unit for representing a huge amount of power, specifically W (Watts). In practical settings, it's impractical to express such a large number in base units (i.e., watts in this case). Therefore, it's typically convenient to use a larger unit prefix to simplify the number. For this question, we need to convert the given amount of power (in watts) into a unit prefix which can express large numbers more simplistically.Among base SI prefixes, "giga-" allows expressing large quantities conveniently—it stands for 10^9 or 1,000,000,000. Therefore, it's appropriate for this context. Converting W into gigawatts, we just divide the power by 1,000,000,000 to get the answer.
