Constant of Proportionality

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.

The Math / Science

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
