One megahertz equals how many hertz?

Explanation:
Understanding metric prefixes helps convert MHz to Hz. Mega means multiply by 10^6, so one megahertz equals 10^6 hertz. Since hertz measure cycles per second, that’s one million cycles per second. The other prefixes describe different magnitudes: kilo is 10^3 Hz (a thousand), milli is 10^-3 Hz (one thousandth), and micro is 10^-6 Hz (one millionth). Therefore, the mapping is 10^6 Hz.
