Convert the volume of ice to the volume of water it will become when melted. Water expands by approximately 9% when it freezes.
Learn how to use the calculator and understand the principles behind ice-water volume conversion
When water freezes into ice, it expands by approximately 9%. This is due to the unique molecular structure of water - hydrogen bonds arrange themselves in a more open structure when water turns to ice, increasing the volume.
The formula used in this calculator is:
Water Volume = Ice Volume × 1.09
For example, if you have 100 cm³ of ice, it will expand to approximately 109 cm³ when it melts into water.
