1 Hz equals how many cycles per minute?

• A. 30 cycles/min
• B. 120 cycles/min
• C. 60 cycles/min
• D. 15 cycles/min

Answer: (C)

Converting frequency units: Hz means cycles per second, so to get cycles per minute you multiply by 60 seconds in a minute. Therefore, 1 Hz equals 1 cycle per second × 60 seconds = 60 cycles per minute. Why the others don’t fit: 0.5 Hz would be 30 cycles per minute (half a cycle per second), 2 Hz would be 120 cycles per minute (two cycles per second), and 0.25 Hz would be 15 cycles per minute (a quarter of a cycle per second).
