Conversion Formula

The constant of proportionality is calculated using the simple formula: k=yxk = \frac{y}{x}k=xy​

Where:

• yyy is the dependent variable.
• xxx is the independent variable.

This formula assumes a direct proportionality between the two variables.

Practical Example

Suppose a car travels 150 km in 3 hours, and you want to find the constant of proportionality for the relationship between distance and time: k=yx=1503=50k = \frac{y}{x} = \frac{150}{3} = 50k=xy​=3150​=50

Here, the constant k=50k = 50k=50 represents the speed of the car in km/h. Using the calculator, you can instantly find this value without manual division.
