Which unit is the standard for measuring frequency?

Which unit is the standard for measuring frequency?

• A. Hertz (Hz)
• B. Newton (N)
• C. Joule (J)
• D. Watt (W)

Answer: (A)

Frequency tells you how many times something repeats each second. The standard unit for that is the Hertz, symbol Hz, named after the physicist Heinrich Hertz. It directly measures cycles per second, which is exactly what frequency is. The other units measure different quantities: Newton is for force, Joule for energy, and Watt for power. So Hz is the correct choice.
