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.
How many units of measurement?
There are exactley 7 units of measurements
What is global standard for measurements?
SI units
What are angular measurements?
If you mean the units, the most commonly used units are degrees, and radians.
What a ratio of two measurements with different units?
Time
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.
What must be true for a ratio of two measurements to be a conversion factor?
For two measurements to be a conversion factor, they must represent the same quantity but in different units. The ratio should equal 1 and can be written as a fraction where the units cancel out, allowing you to convert from one unit to another.

Why do we prefer to use metric units of measurements over English units of measurements?
Metric units of measurement are more fun to say.
1-200 in si units?
1-200 in SI units typically refers to the range of values for measurements such as length, mass, time, etc., which are expressed using the International System of Units (SI). For example, 1-200 meters for length, 1-200 grams for mass, and 1-200 seconds for time.
