In this example the strength (concentration) of the alcohol spirit has been specified as 40 Volume % at 20C and the AlcoDens calculator gives the freezing point as -23.3C.

freezing point strength calculator

In this example the strength (concentration) of the alcohol spirit is being calculated. The temperature has been specified as -60F and the AlcoDens calculator gives the strength of the strongest blend that would freeze as 150.60 Proof @60F.

As can be seen in the screen shots above, the strength of the alcohol and water blend can be specified as a mass strength, a volume strength (ABV) or as Proof @60F. You can also select the units for temperature for the freezing point.

The calculator covers the range from a freezing point of 0C (32F) corresponding to pure water down to -115C (-175F) corresponding to an alcohol strength of about 95% ABV (190 Proof @60F).
