Constant of Proportionality Formula
The following formula is used to calculate a constant of proportionality.
C = X / Y
- Where C is the constant of proportionality
- X is a variable directly dependent on Y
- Y is a variable directly dependent on X
Constant of Proportionality Definition
A constant of proportionality is a value that directly relates two variables two one another. For example, let’s take to variables X, and Y to be directly dependent in the form above. So C = X/Y, so X = C*Y, and Y= X/C.
Constant of Proportionality Example
In this example, the variables are inversely proportional. Let’s say we have X which we know is 5, and we have the constant of proportionality of 2. We can then find Y by rearranging the equation Y = X/C = 5/2 = 2.5.
The constant of proportionality can be used to calculate the missing variable.
A constant of proportionality represents the ratio of two different variables to one another.
