This is why seawater at Antarctica is very salty.

The salt that is rejected forms brine beneath the ice and becomes more and more salty until it becomes so dense that it sinks, displaces less dense seawater that moves to the surface. As ice forms in the sea, the salt cannot form part of the ice crystal so the ice is almost pure water.

The output density is given as g/cm 3, kg/m 3, lb/ft 3, lb/gal(US liq) and sl/ft 3. Sea water has 30000 to 40000 ppm (parts per million) = mg/L salinity. The calculator below can be used to calculate the liquid water density at given temperatures. When read from the lowest point of the meniscus, the correct reading is 30.0 mL. The graduated cylinder markings are every 1-milliliter. The maximum density of pure water at a pressure of one standard atmosphere is 999.972 kg/m 3 at a temperature of 3.98 ☌ (277.13 K), that is 0.999 972 kg/L.Ĭalculation of water density (density of water H 2O) Water temperature The accuracy of the experimentally determined density of water will then be evaluated by comparison to the true, accepted density of water. Maximum density of pure water was 1.000 kg/L. Helium has a density of 0.1785 kg/m 3 = 0.1785 g/L = 0.0001785 kg/dm 3 = 0.0001785 kg/L =įrom 1901 to 1964, a litre was defined as exactly the volume of 1 kg of water at maximum density, and the

Water has a density of 1000 kg/m 3 = 1000 g/L = 1 kg/dm 3 = 1 kg/L = 1 g/cm 3 = 1 g/mL. It is exactly 1000 kg/m3 at 4 degrees Celsius. But you’re right that it does vary a little bit with temperature. The correct SI unit of denstity of water is " ρ = 1000 kg/m 3". In general, we say that the density of water is 1000 kg/m3 (or 1 g/cm3). Water is the reference with its highest density at 3.98☌ ( ρ = 1 g/cm 3) The logic is to divide the value of kg/m 3 by 1000 to get pure water. In other words, at the same temperature, the density of water in g/ml (or g/cm 3) is 0.99777. At room temperature (i.e., 22° C), the density of water in kg/m 3 is 997.77. Many people still use g/cm 3 (gram per cubic centimeter) or kg/L (kilograms per liter) to measure density. With respect to the definition, the density formula is represented as Density () Mass (m)/Volume (V). You can also enter the density in g/cm³, the mass in g, and the volume in cm³.ĭensity conversion factors from non-SI units Unit Please enter two values, the third value will be calculated.
