As usual, there should be a bit of flexibility in there. I am not saying "oh, it's 0C, therefore ALL water in all town is frozen , lets wait until it gets to 1C so all water melt". But more on the line "oh, its around 0C (+ or - 5C), lets be careful while driving because some of the streets might have ice". Farenheit freezing temp is 32 I think? Thats VERY arbitrary. A lot more than C.

    • or - 5°C

    23°F to 41°F is -5°C to 5°C

    If it's below 40°F I'd be cautious of Ice. Once again, it doesn't matter that water freezes at exactly 32°F at standard pressure.

    It's like boiling water. No one puts a thermometer in water to make sure that it hits 100°C exactly.

    150°F water will scald you in a second (65°C)

    140°F water will scaled you in 3 seconds (60°C)

    120°F water will scaled you in 10 minutes (50°C)

    +100°F water has the potential to scaled you (~40°C)

    I'd rather know that +100°F water has a chance to burn me than remembering +40°C has a chance.

    That's way more important knowledge than the freezing and boiling temperatures of water at standard pressure.
