Duty cycle vs hertz

WebHow to convert hertz to cycles per second [Hz to cycle/s]: f cycle/s = 1 × f Hz. How many cycles per second in a hertz: If f Hz = 1 then f cycle/s = 1 × 1 = 1 cycle/s. How many cycles per second in 99 hertz: If f Hz = 99 then f cycle/s = 1 × 99 = 99 cycle/s. Note: Hertz is a metric unit of frequency.
