Ice melts at 0 °C (32 °F) under normal atmospheric pressure.

Quick Scoop

  • Pure ice at standard pressure starts to turn into liquid water once it reaches 0 °C / 32 °F.
  • While the temperature stays at 0 °C during melting, extra heat energy goes into breaking the ice’s molecular bonds instead of raising the temperature.

A bit more detail

  • The exact melting point can shift slightly if pressure changes, but for everyday situations (roads, drinks, weather), 0 °C / 32 °F is the rule‑of‑thumb.
  • Impurities like salt can lower this melting point, which is why salted ice can start to melt below 0 °C.
