Constant of Variation Calculator: Determine K for Direct & Inverse Relationships

Calculate Your Constant of Variation


Use our free Constant of Variation Calculator to quickly find the proportionality constant (k) for both direct and inverse variation. Simply input your X and Y values, select the variation type, and get instant results. Perfect for understanding how variables relate in mathematical and scientific contexts.

Formula:

The constant of variation (k) describes the relationship between two variables, x and y.

  • For Direct Variation, the formula is: k = y / x
  • For Inverse Variation, the formula is: k = x * y

Where:

  • k is the constant of variation
  • x is the independent variable
  • y is the dependent variable
