Freezing Temps  The temperatures at which various KOH
concentrations will freeze can be found in the charts below. One
chart is for Fahrenheit and the other is for Centigrade.  As an
example, lets say we want a 20% solution. You would use 200
grams of KOH with 800 ml of water. 1 ml of water = 1 gram. This
would make a 20% solution of KOH by weight. That's how the
charts below are calculated.  Note: These charts show the
freezing temps down to a theoretical maximum. In actual practice
you will find that you don't get much benefit going higher than
28%. The reason is that the solution becomes saturated with
chemical, and after that point, no further chemical will
dissolve. That means that more chemical will just be floating in
your electrolyte, clogging up any check valves or small
orifices. The amount of chemical that will dissolve increases
with increases in temperature. Therefore at very low temps, less
chemical will dissolve and therefore provide less
