## pKa to Ka calculator

The F Ratio Calculator is a statistical tool used to assess the significance of differences between groups in an analysis of variance (ANOVA). It helps determine if the variation among group means is statistically significant. The F ratio is calculated by dividing the variance between groups by the variance within groups.

### Formula

The formula for calculating the F ratio is:

F = Variance between groups / Variance within groups

### Example

Suppose we have an input field where you can enter the pKa value. Let’s say you enter a pKa value of 3.

Calculating the F ratio: Ka = 10^(-pKa) = 10^(-3) = 0.001
