"...
At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml,
1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft
At 4°C pure water has a specific gravity of 1. ( Some reference the s.g. base temperature as 60F.)
Water is essential for life. Most animals and plants contain more than 60 % water by volume.
More than 70 % of the Earth's surface is covered with about 1.36 billion cubic kilometers of water / ice
The density of pure water is a constant at a particular temperature, and does not depend on the size of the sample. That is, it is an intensive property. The density of water varies with temperature and impurities.
Water is the only substance on Earth that exists in all three physical states of matter: solid, liquid and gas.
When water freezes it expands rapidly adding about 9 % by volume. Fresh water has a maximum density at around 4° Celsius. Water is the only substance where the maximum density does not occur when solidified. As ice is lighter than water, it floats.
Water has a very simple atomic structure. This structure consists of two hydrogen atoms bonded to one oxygen atom - H2O
Note; kg/m3 divided by 16.02 = lbs/cu.ft. kg/m3 divided by 1,000 = g/ml
Convert g/cm3 = g/cc = g/ml = g/mL - they are all the same. ..."

Liquid is densest.. That's why ice floats, because it is less dense.
