Final answer:
The measure of clock speed that equals one million cycles per second is 1 MHz.
Step-by-step explanation:
The measure of clock speed that equals one million cycles per second is 1 MHz (megahertz). The unit of frequency used to measure clock speed is hertz (Hz), and 1 MHz is equal to 1 million hertz. It represents the number of cycles or operations a computer's processor can perform in one second.
