Why is a ratio expressed without writing units?
In a ratio of measurements for the same kinds of units, units get canceled. For example, in a ratio of 3 meters / 8 meters, you can cancel the "meters" in the numerator and the denominator. An important ratio is pi, which is the ratio of the circumference of a circle to its diameter. If you measure the circumference in feet, and the diameter in feet, then divide circumference/diameter, then the result is the dimensionless quantity 3.14159265.... If you go back and measure both in meters, you get the same answer.In a ratio of two measurements, the units cancel, so it makes no difference whether you write the units, or not.

Is it true that z values have no units of measurements?
It is true; the z value has no unit of measurement. The formula for z is: (x-mu)/sigma and the units in the numerator and denominator cancel out.
