One million watts is equivalent to how many megawatts?

• A. One
• B. Ten
• C. One hundred
• D. One thousand

Answer: (A)

One million watts is equivalent to one megawatt because the term "megawatt" is defined as one million watts. The prefix "mega-" denotes a factor of one million in the International System of Units (SI). Therefore, when converting watts to megawatts, you divide by one million. Since there are one million watts in a megawatt, the correct relationship is that one million watts translates directly to one megawatt. Understanding this relationship is essential in electrical work, particularly in contexts such as power generation, where power levels are often expressed in megawatts for the sake of simplicity and ease of comprehension.
