1 megahertz (MHz) equals how many hertz (Hz)?

• A. 1,000,000 Hz
• B. 10,000 Hz
• C. 1 million Hz
• D. 1000 Hz

Answer: (C)

Frequency measurements use hertz, which are cycles per second. The prefix mega means a factor of one million. So 1 megahertz is 1 × 10^6 hertz, which equals one million hertz. In digits, that’s 1,000,000 Hz, the same quantity described in a different form.
