Enter the values of two directly proportional variables into the calculator to determine the proportionality constant. This calculator helps in finding the constant of proportionality (k) when two variables are known to be directly proportional.

Proportionality Constant Formula

The following formula is used to calculate the proportionality constant.

k = y / x

Variables:

  • k is the proportionality constant
  • y is the value of variable A
  • x is the value of variable B

To calculate the proportionality constant, divide the value of variable A (y) by the value of variable B (x).

What is a Proportionality Constant?

The proportionality constant is a constant value that relates two variables that are directly proportional to each other. In the equation y = kx, k is the constant of proportionality that describes how the value of one variable (y) changes when the other variable (x) changes. This constant is a fundamental concept in various fields such as physics, mathematics, and engineering.

How to Calculate Proportionality Constant?

The following steps outline how to calculate the Proportionality Constant.


  1. First, determine the value of variable A (y).
  2. Next, determine the value of variable B (x).
  3. Use the formula k = y / x to calculate the proportionality constant (k).
  4. Finally, enter the values of y and x into the calculator to find the constant k.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Variable A (y) = 50

Variable B (x) = 10
