Enter the freezing point depression constant and the molality into the calculator to determine the freezing point of the liquid. This calculator can also evaluate the depression constant or molality given the other variables.

Freezing Point Formula

The following equation is used to calculate the freezing point of a liquid.

T = Kf * m 
  • Where T is the freezing point
  • Kf is the freezing point depression constant
  • m is the molality

To calculate the freezing point, multiply the freezing point depression constant by the molality.

Freezing Point Definition

A freezing point is a temperature at which a liquid transition to a solid.
