This postulate allows mathematicians to define coordinate systems. Coordinate systems allow us to graph mathematical models. Notice that this postulate does not define a unit of measure, it only tells us that a unit of measure is defined by assigning the values of 0 and 1 to two points. The 'ruler' used may be a metric ruler, an english ruler or even a clock. As long as a number can be assigned to a point on a dimension, this postulate applies.
