Hertz
Hz is hertz which measures sound.
Oh, dude, those are all units of measurement in physics! Like, Volt measures electrical potential, Joule measures energy, Ohm measures resistance, Kelvin measures temperature, Ampere measures electric current, Farad measures capacitance, and Hertz measures frequency. So, yeah, they all have in common that they're units used to quantify different physical quantities.
These are two completely different units of measure. MHZ (megahertz) measures frequency as cycles per second. MB (megabytes) measures memory storage.

Conversion factors (equivalence between two measures) are used to convert between units
Units that are used for measures in which the direction is relevant. Example are displacement, velocity, acceleration, force.
The unit that measures wave frequency is hertz (Hz).
Several units are used, depending on what you want to measure. For example, in the case of sound, you can use units of energy, of intensity (energy/area), of wavelength, frequency, speed, and probably a few more.
Ultrasonic units can penetrate solids, liquids, and gases, depending on the frequency used. Higher frequency ultrasonic waves penetrate shallow tissues or liquids, while lower frequency waves can penetrate deeper tissues or solids.
The conversion of different units of measures used on a map
They are 15 and 45 units.
Partial productivity measures are indicators used to analyze activities in terms of a single input (e.g., units produced per worker, units produced per plant, units produced per hour, or units produced per quantity of material).
