It may be just about any unit of speed. You can't derive the unit from the number. In physics, it is quite common to measure speeds in meters/second, but it can be just about any other unit of speed as well.
frequency of a wave times its wavelength
Wave speed = (Wavelength) times (frequency).
A ml is one unit, so 15 units of them would make 15 ml.
The number of soundwaves, or any type of wave, is known as the frequency. You can use the V=Fλ equation to calculate the other properties of a wave (V = wavespeed, F = Frequency and λ = wave length). So really, if you change the frequency of a wave, you also change the wavespeed and the wavelength, as they are directly related by this equation.
15 pounds is 6.8 (6.80389) kg
frequency of a wave times its wavelength
frequency=wavespeed divided by wavelength.
To get the wavelength of a wave simply divide the wavespeed with its frequency.
Wave speed = (Wavelength) times (frequency).
Phase velocity.
Wavespeed = frequency x wavelength
the wavespeed
15 dollars/hour is the unit rate
A ml is one unit, so 15 units of them would make 15 ml.

15 x 15 is a square unit whereas foot is a linear unit. A linear unit can be said to have either zero or infinite width which means that either no matter how many feet you have you will never cover any area 15 x 15 or 15 x 15 is as near to zero feet as makes no odds.
