**Constant of proportionality calculator** is an effective free online tool that was created to help students and people in general, solve their mathematical problems of proportionality at home without any stress or complication.

**Constant of proportionality is a sequence of two numbers that are directly or indirectly proportional if their consisting elements have a constant ratio**.

When two values are related to each other through ratio, this sort of relationship is called a **proportional relation**.

You will come across many different names for the constant of proportionality i.e. **constant ratio**, **constant rate**, **unit rate**, **constant of variation** and **rate of change**. It is denoted by ‘**K**’.

For finding the constant of proportionality; you have to write the ratio in a fraction form first, then divide the denominator with the numerator and this is how you will get the constant of proportionality.

Now, manually carrying out such calculations especially if you are weak in math can be very time-consuming and stressful.

There is a high chance that you might not get the correct answer and make several mistakes through the process that affects your overall result.

That is why the **constant of proportionality** calculator is constructed in a way that will provide you with fast and precise answers.

In a proportionality fraction; **K** determines the relation between the two values (how they are related to one another).

You will find innumerable examples of constant of proportionality not only in mathematics but in physics, chemistry and statistics as well.

For example; if an object is travelling at a constant speed, then the distance will be directly proportional to the time used for travelling, with the speed being the constant of proportionality.

But if we look at the mathematical example, it will be clearer to you.

For example; **y** = price (dollars), **x** = gas (gallons) and **k** = amount of money that you will pay at the gas station.

**y = kx (price is directly proportional to the gas pumped)**

**Constant of proportionality calculator** is here to help you calculate the ratio between the two given dependable values.

This helps you understand how the dependable variable will change with the independent variable. The more the constant of proportionality; the more the dependable variable will change with the independent variable.

The constant of proportionality is the unit of a linear relation which is why in a graph it is called a **slope** or a **gradient**.

Mostly it is expressed in a fraction or a decimal because the dependable variable is divided by the independent variable.
