A beta version of a calculator that uses the results of a titration with NaOH to calculate the % lactic acid, Soxhlet Henkel degrees, Thörner degrees, Soxhlet Henkel degrees and Dornic degrees of a milk sample has been added. Users may vary the molarity of the NaOH solution, note normality and molarity are identical for NaOH, and the volume of milk used. An accompaning tutorial that provides the underpinning science remains to be added.
