Ice is less dense than liquid water — that's why it floats. With a density of about 0.92 g/ml, 100 grams of ice takes up approximately 109 ml of space, about 9% more volume than the same weight of liquid water.
This expansion is unique to water: most substances shrink when they freeze. Understanding ice density matters for cocktail recipes, cold chain logistics, and food science. For all conversions, use our gram to ml converter.
