You don't. Those two are completely unrelated, so you don't convert from one to the other.
You multiply it by 1000.Would you believe megaHertz, to Hertz, multiply by 1000 000.
the number of hertz = count per second
There is nothing to convert. You are using the same unit of measurement. A hertz is a hertz, all you are dealing with is 10 less Hertz. 60 Hertz - 10 Hertz = 50 Hertz The difference is 10 Hertz. The math there is just to give you a clear example and illustrate my point. What you are asking for is similar to someone asking "how do you convert miles to miles" or "how do I convert inches to inches".
To convert seconds to hertz, you simply take the reciprocal of the time in seconds. For example, if you have a time of 0.5 seconds, the conversion to hertz would be 1 / 0.5 = 2 hertz. Hertz is the unit of frequency, representing the number of cycles per second.
no.

You don't. Hertz and meters measure two completely different things.
kHz means 1000 hertz. To convert from kHz to hz, multiply the number of kHz by 1000 and the product will be in hertz.
Centimeter is a unit of length, Hertz is a unit of frequency; any conversion is possible.
Cycles per second = Hertz. In other words they are the same.
That is possibly the input impedance of a loudspeaker - not an impedance of an amplifier.
To convert milliseconds to hertz, use the formula: Hz = 1000 / ms. Therefore, for 4 ms, the equivalent frequency in hertz would be 250 Hz.
