One megahertz (abbreviated: MHz) is equal to 1,000 kilohertz, or 1,000,000 hertz. It can also be described as one million cycles per second. Megahertz is used to measure wave frequencies, as well as the speed of microprocessors. Radio waves, which are used for both radio and TV broadcasts, are typically measured in megahertz.
But bigger still by a factor of about 16 is the megaparsec, defined succinctly as follows: one million parsecs. As a result, the team said it measured Hubble's constant at 70 kilometers per second per megaparsec (a megaparsec is 3. 7 billion years and an expansion rate of 71 kilometers per second per megaparsec. 1], about 62 km per second per megaparsec, an acceptable value [8].
