The constant of proportionality, often denoted by k, quantifies the relationship between two variables that are directly proportional, meaning that they vary at a constant rate. This concept finds widespread application in various scientific disciplines, engineering, and real-world scenarios. Our online constant of proportionality calculator empowers you to effortlessly compute k and analyze direct variation with ease.
Direct variation describes a linear relationship where the change in one variable corresponds directly to a proportional change in the other. Mathematically, this relationship can be expressed as y = k * x, where:
To determine the constant of proportionality, two data points from the direct variation relationship are required. The formula for calculating k is:
k = y / x
Our online calculator automates the process of finding the constant of proportionality. Simply enter the values of y and x for any two points on the line of direct variation, and the calculator will instantly compute k.

Field | Application |
---|---|
Physics | Acceleration, Velocity |
Chemistry | Concentration of Solutions |
Economics | Supply and Demand |
Biology | Growth Rate of Organisms |
Engineering | Structural Design |
Equation | Relationship |
---|---|
y = 5x | Velocity is directly proportional to acceleration (5 m/s²) |
y = 0.1x | Volume is directly proportional to concentration (0.1 L/M) |
y = -2x | Price is directly proportional to the number of goods supplied (-2$/unit) |
y = 3.5x | Weight is directly proportional to the number of animals (3.5 kg/animal) |
Error | Reason |
---|---|
Using only one data point | Requires at least two data points |
Dividing by zero | Independent variable (x) cannot be zero |
Assuming non-direct variation | Not all linear relationships are directly proportional |
Misinterpreting the slope | Slope is not always the same as the constant of proportionality |
