`k = "y" / "x" `

Enter a value for all fields

The **Constant of Proportionality** calculator computes the constant of proportionality based on the two related values (x and y).

**INSTRUCTIONS:** Enter the following:

- (
**y**) Dependent Value (aka range) - (
**x**) Independent Value (aka domain)

**Constant of Proportionality (k):** The calculator returns the proportional value.

If two values (x and y) are proportionally related, one can express their relationship in the formula:

y = x * k

where:

- y = the dependent value or range
- x = the independent value or domain
- k = the constant of proportionality

To find the constant of proportionality, one divides both sides of the equation by x and gets:

y/x = k
