# General Water Information

Without water, there is no life on our Earth. In the information below, you will find some interesting general data about water. We strongly implore you to conserve our natural resources, all of the, but especially our water. Wasting water is a lethal mistake. See other water links at the bottom of this informational page.

 At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml, 1 kg/liter, 1000 kg/cu.m, 1 ton/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.

To use the table below, run down the left column for whole degrees then move across for tenths of a degree.
For example, the row/column shaded in aquamarine shows the density of pure water at 17.7°C = 0.998650 grams/cm3
