True or False: The metric prefix for 1,000,000 is Mega or M.

The statement is true because the metric prefix "Mega," denoted by the symbol "M," represents a factor of one million (1,000,000) in the International System of Units (SI). This prefix is commonly used across various scientific and engineering disciplines, including electrical engineering, where it denotes quantities such as megawatts (MW) for power and megahertz (MHz) for frequency. The definition of "Mega" is universally recognized and applies consistently in contexts involving measurements, not limited to electrical terms, making the assertion accurate.

While it’s important to note that context can dictate how prefixes are used—for instance, in computing, "mega" might sometimes refer to 1,048,576 due to binary interpretations—this does not change the fact that, in the SI metric system, it definitively stands for 1,000,000.
