Ice and Water - Melting Points vs. Pressure

Online calculator, figures and tables with melting points of ice to water at pressures ranging from 0 to 29000 psia (0 to 2000 bara). Temperature given as °C, °F, K and °R.

Melting point: The temperature at which a solid turns into a liquid.

The melting point of water is dependent of the pressure above the ice (solid water), and the melting point or freezing temperature decreases with increasing pressure. By definition 0 °C is at the melting point of water at 1 atmosphere pressure.

Online Ice to Water Melting Point Calculator

The calculator below can be used to calculate the water melting point at given pressures.
The output temperature is given as °C, °F, K and °R.

Note! Pressure must be within the ranges 0.01-2000 bara, 0.1-29 000 psia, 5-1500 000 mm Hg or 0.2-59000 in Hg.

Choose the actual unit of pressure:

See Water and Heavy Water for thermodynamic properties at standard condtions.
