Water normally freezes at 0 degrees Celsius, which is 32 degrees Fahrenheit (about 273.15 Kelvin).

If you want the “full story” behind this:

  • For everyday life (puddles, ice cubes, car windshields), think: 0 °C / 32 °F = freezing point of water.
  • Scientists define this as the temperature where liquid water turns into solid ice at normal atmospheric pressure.
  • In real-world conditions, impurities and pressure can shift the exact freezing behavior a bit, but it still happens around 32 °F on Earth’s surface.
  • In very pure, calm conditions, water can “supercool” and stay liquid below 0 °C before it suddenly freezes, but that’s a lab or cloud-physics sort of situation, not your kitchen freezer.

So for the question “atwhat temp does water freeze,” the practical answer you’d give on a forum or in class is: 0 °C (32 °F).
