To measure a physical quantity correctly and need to compare it with some standard quantities. Thus a standard unit is needed to measure a quantity correctly.
The standard unit to measure mass is kilograms.
It depends on what you are trying to measure. There are different standard units for different characteristics.
Standard International unit (SI unit)
Hertz (Hz) is the SI unit of frequency, equal to one cycle per second.
Hertz, hz= 1/second is the unit measure of frequency.
The unit measure of frequency is hertz (Hz), which represents the number of cycles or repetitions of a wave occurring in one second.

The unit used to measure the frequency of sound is hertz (Hz).
The unit to measure frequency of a sound wave is Hertz (Hz). It indicates the number of cycles or vibrations per second.
This unit is megahertz (MHz).
Hertz is a unit to measure frequency. Number of waves passing through a particular point in unit time is considered to define frequency. The unit for frequency is inverse seconds.

The cgs unit to measure frequency is hertz (Hz). It represents the number of cycles or oscillations per second.
Frequency has the dimensions of reciprocal time. The unit is "per second" also called "Hertz".
