I might be alone on this but the freezing point of water is almost irrelevant in daily life. Any precipitation from 30°F (-1°C) to 35°F (1.5°C) results in some mix of snow/slush. Less than that and it’s snow/ice.
However if you live somewhere where they use salt as a de-icer, knowing the freezing point of saltwater (0°F, -17.7°C) is very, very important.
