What value does the SI prefix "mega (M)" represent?

The SI prefix "mega (M)" represents a factor of one million, which is mathematically expressed as (10^6). This means that when you see "mega" in a measurement, it indicates that the value is multiplied by one million. For instance, a megawatt (MW) is one million watts, and a megabyte (MB) is one million bytes. Understanding the significance of the prefix "mega" is essential in various fields, especially in engineering and science, where precise measurements and values are crucial.

In the options provided, "C" correctly identifies this value, establishing "mega" as a designated factor of (10^6) or one million. This makes it critical for interpreting and converting measurements appropriately across different contexts.
