If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them.
In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.

Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.
It is the constant of proportionality.
Weber's Law"Ernst Weber noted that for people to really perceive a difference, the stimuli must differ by a constant "proportion" not a constant "amount."

The Circumference of a circle is directly proportional to the diameter. The constant of proportion is 'pi = 3.141592....'. Another one is force is directly proportional to mass. The constyant of proportion is acceleration.

Pi is a constant because it is the ratio of the circumference to the diameter of a circle and they are always in the exact same proportion.
It means that different compounds composed of the same elements have their own unique proportion of those elements. For example, both water (H2O) and hydrogen peroxide (H2O2) are composed of hydrogen and oxygen. However, the proportion of hydrogen to oxygen in water is 2 to 1, and the proportion of hydrogen to oxygen in hydrogen peroxide is 1 to 1.
